Quick reference

Architecture, Deployment, and Licensing

  • XIQ-SE is a single-server or distributed deployment: the main (application) server hosts the GUI, NAC, and databases, while remote servers host distributed services such as captive portal, RADIUS/802.1X authentication, and site-local engines.

  • Core components: the Site Engine application server, Extreme Control (NAC), Extreme Analytics, one or more ExtremeCloud IQ Controller (wireless) instances, and ExtremeCloud IQ (cloud) integration for wireless management.

  • The application server runs on a hardened Linux appliance image or as a virtual appliance; management is through a web GUI on HTTPS (default 8443) and CLI via console/SSH.

  • Licensing is feature-based and per-device/per-seat: base Site Engine, Extreme Control (device count), Extreme Analytics (flow source count), and wireless controller licenses are separate entitlements.

  • License entitlement is enforced by device count; exceeding the licensed device count for a feature disables onboarding of additional devices for that feature until licenses are added or devices are removed.

  • A distributed deployment requires network reachability between servers on the documented ports; the application server must reach remote servers for authentication, portal, and data collection traffic.

  • The appliance database (PostgreSQL-based) and file stores are local to each server; backup and restore must be planned per server, and distributed servers must be backed up consistently.

  • Capacity planning depends on managed device count, monitored ports, flow rate for Analytics, and NAC authentication rate; scale guidance is per appliance size (small/medium/large).

Site Engine Installation, Upgrade, and Initial Configuration

  • Initial setup is performed through the console/CLI first-time configuration: set hostname, management IP, netmask, gateway, DNS, NTP, and the admin password before accessing the web GUI.

  • NTP synchronization is mandatory for correct certificates, logs, NAC session timing, and distributed server trust; configure at least one reliable NTP source during initial setup.

  • The initial web GUI wizard covers license installation, database initialization, and administrator account creation; complete it before adding devices.

  • Upgrades are performed with the application upgrade image uploaded through the GUI or CLI; take a full backup and verify free disk space before starting.

  • Upgrade path rules apply: some releases require an intermediate version before jumping to the target; check the release notes' supported upgrade path from the currently installed version.

  • Distributed deployments must be upgraded in the correct order (typically remote/distributed servers before or in coordination with the application server), following the release notes.

  • After upgrade, verify services start, check the server health/status page, and re-validate licenses and integrations (wireless controllers, cloud connection, RADIUS).

  • Firmware for managed Extreme devices is stored in the Site Engine image repository; device firmware images are added separately from the Site Engine upgrade image.

Device Discovery, Onboarding, and Inventory Management

  • Discovery methods: subnet/range scan, seed device (walks neighbors via LLDP/CDP/EDP/FDP), CSV import, and auto-discovery of devices that report in (e.g., via ExtremeCloud IQ or DHCP/registration).

  • SNMP credentials (v2c community or v3 user/auth/priv), CLI credentials (SSH/Telnet), and device profiles determine whether a discovered device can be onboarded and managed.

  • Device families have profiles that define the credential set, firmware, and configuration templates applied at onboarding; a device must match a profile to be fully managed.

  • Onboarding enforces licensing: a device is only added to inventory as managed if a license is available for its feature set (wired, wireless controller, NAC).

  • Inventory views group devices by family, firmware version, site, and management status; unmanaged/unknown devices remain visible until credentialed or deleted.

  • Site assignment determines which maps, policies, and role-based access apply to a device; devices can be moved between sites after onboarding.

  • Device configuration changes can be pushed from Site Engine (templates, firmware) or made locally; a resync/re-read updates Site Engine's view of the device.

  • Bulk operations (firmware upgrade, configuration deploy, delete) are scheduled as jobs and tracked in the job/task status view.

Quick reference

Network Topology, Maps, and Site Hierarchy

  • The site hierarchy is a tree: World > Region/Country > Site > Building > Floor; devices, maps, and policies are bound at the appropriate level.

  • Topology maps are auto-generated from neighbor discovery (LLDP/CDP/EDP/FDP) and can be manually adjusted; link status and device health are reflected in map colors.

  • Floorplan maps are image-based; devices are placed on the floorplan and AP placement drives wireless coverage/heat-map views.

  • Site-level policy inheritance flows down the hierarchy; a policy set at a parent site applies to children unless overridden.

  • Topology views can be filtered by site, device family, or link type to isolate segments; the physical topology differs from the logical/VLAN view.

  • Map status propagates device alarms to the map icon; a red icon indicates a critical alarm on that device or link.

  • Devices not assigned to a site appear in a default/unassigned location; assigning them to a site is required for site-scoped policy and reporting.

Policy and Role-Based Access Control (Control, Access Control, and Fabric)

  • Extreme Control NAC evaluation order: authentication (802.1X/MAC/WebAuth) → authorization (rules/roles) → enforcement (VLAN, ACL, reauthentication, posture).

  • Rules are evaluated top-down within a rule set; the first matching rule's role/action applies, so order and specificity matter.

  • Roles define network access: VLAN assignment, ACL/filter, bandwidth, and reauthentication period; roles are mapped to devices/ports via device configuration.

  • Policy domains separate wired, wireless, and VPN policy; each domain has its own rule sets and role mappings.

  • Fabric (Extreme Fabric Connect / SPBM) integration uses I-SIDs and VSNs to place authenticated users into a service; NAC role maps to a fabric service/VLAN.

  • Guest and BYOD flows use captive portal + registration; device registration state and MAC caching determine subsequent authentication without portal.

  • Policy simulation/test tools let you validate which rule and role a given set of attributes (user, MAC, device, location) will match before deploying.

Wireless Management and ExtremeCloud IQ Integration

  • ExtremeCloud IQ Site Engine can manage ExtremeCloud IQ Controller (formerly WiNG/ExtremeWireless controllers) on-premises and integrate with ExtremeCloud IQ (cloud) for cloud-managed APs.

  • On-premises wireless controllers are onboarded with SNMP/CLI credentials and a controller profile; APs are then adopted through the controller and appear in Site Engine inventory.

  • Cloud integration uses an ExtremeCloud IQ connection (API credentials/token) so cloud APs, sites, and clients appear alongside on-premises wireless in Site Engine.

  • Wireless views include AP status, client associations, SSID/VLAN mapping, and RF health (channel, power, interference, retries).

  • AP firmware and configuration templates are pushed through the controller or cloud; Site Engine orchestrates but the controller applies the config.

  • Client troubleshooting uses the client detail view: association history, authentication events, roaming, and the serving AP/controller.

  • SSID-to-VLAN-to-role mapping ties wireless policy to NAC: the SSID determines the policy domain and the resulting role/VLAN for the client.

Monitoring, Alarms, Events, and Reporting

  • Alarm severity levels (critical/major/minor/warning/info) drive map colors, notification, and dashboard counts; alarms are cleared or acknowledged by operators.

  • Events are raw log/trap records; alarms are derived from events by alarm rules/correlation. Both are searchable in the events/alarms views.

  • SNMP traps, syslog, and syslog-based flow data feed monitoring; ensure devices are configured to send traps/syslog to the Site Engine server address.

  • Dashboards and reports cover device health, port utilization, wireless clients, NAC authentications, and alarm trends; reports can be scheduled and exported.

  • Thresholds (interface utilization, device reachability, wireless health) generate alarms when crossed; thresholds are configurable per device/port.

  • Alarm notification can be delivered by email and SNMP trap forwarding; notification targets are configured in the administration settings.

  • Report data retention depends on the database and purge settings; long-term trending requires adjusting retention or exporting reports.

Quick reference

Administration, User Accounts, Backup, and High Availability

  • Local user accounts have assigned authorization groups (roles) that control GUI/CLI access and which device/site scopes they can manage.

  • External authentication (RADIUS, LDAP/AD, TACACS+) can be used for administrator login; group mapping maps external groups to Site Engine authorization groups.

  • Backup captures the database and configuration; schedule regular backups and store them off-box. Restore requires a matching or compatible software version.

  • High availability options include distributed/remote servers for service redundancy and database replication/failover configurations per deployment guide; HA must be designed before deployment.

  • Audit logs record administrative actions (logins, config changes, policy edits); review them for change tracking and compliance.

  • Certificate management: replace the default self-signed web certificate with a CA-signed certificate for trusted HTTPS access.

  • Server maintenance tasks (database purge, log rotation, disk cleanup) are scheduled; monitor disk usage to avoid service degradation.

Quick reference

Troubleshooting, Diagnostics, and Automation

  • Diagnostic tools include ping/traceroute from the server, SNMP walk/test, CLI credential test, and device reachability checks from the device detail view.

  • NAC troubleshooting follows the authentication chain: supplicant → switch/AP → RADIUS → Site Engine policy → role/VLAN enforcement; check each hop's logs.

  • Common onboarding failures: wrong SNMP/CLI credentials, unreachable management IP, unsupported firmware, missing license, or no matching device profile.

  • Logs to inspect: server logs (application, NAC, database), device syslog, and RADIUS authentication logs; increase log verbosity temporarily when diagnosing.

  • Automation uses the REST API and/or CLI scripting to create devices, sites, policies, and reports; API access requires an account with appropriate authorization.

  • Scheduled jobs (firmware, config deploy, reports, backups) show status and error detail in the job/task view; failed jobs can be retried.

  • Health checks: verify services are running, NTP is synced, disk space is sufficient, and licenses are valid before escalating a support case.
