ExtremeCloud IQ licensing tiers

Connect, Pilot, and CoPilot are the subscription tiers; each tier unlocks a different set of management, analytics, and AI-driven features per onboarded device.

Universal switch platform

Extreme switches such as the 5420, 5520, and 5720 can run either ExtremeXOS or VOSS, selected by loading the appropriate software image on the device.

Fabric Engine

The VOSS-based fabric software that implements SPB/IS-IS Fabric Connect on supported Extreme switches, replacing spanning tree in the fabric core.

ExtremeCloud IQ Controller

The on-premises wireless controller option for environments that cannot use the cloud management plane; it manages access points and pushes SSID and policy configuration.

License consumption trigger

An ExtremeCloud IQ device consumes a subscription license when it connects to the tenant and is onboarded, identified by its serial number.

Collapsed core design

A campus topology that merges the distribution and core layers into one layer, reducing hop count and cost while keeping policy at that boundary.

Oversubscription ratio

The ratio of downlink bandwidth to uplink bandwidth at a switch or leaf; a 3:1 ratio means downlinks can offer three times the uplink capacity.

PoE+ power budget

802.3at supplies up to 30 W per port at the PSE; the switch total budget must cover the sum of all powered ports simultaneously.

Jumbo frame requirement

An MTU near 9000 bytes must be configured consistently on every hop for storage and vMotion traffic; one mismatch causes silent frame drops.

DSCP trust boundary

The point in the network where QoS markings are trusted; typically set at the access edge so downstream devices preserve the classification.

Spine-leaf ECMP

A data center topology where every leaf connects to every spine and traffic is load-balanced across equal-cost paths, giving predictable latency between any two hosts.

ExtremeXOS save command

Running 'save configuration' writes the running configuration to non-volatile storage; changes not saved are lost after a reboot.

VOSS VLAN creation

On VOSS, create a VLAN with 'vlan create <id> name <name>' and add ports with 'vlan members add <id> <ports>'.

ExtremeXOS IP binding

On ExtremeXOS, an IP address is bound directly to a VLAN using 'configure vlan <name> ipaddress <ip> <mask>', which creates the L3 interface.

VOSS IP interface

On VOSS, Layer 3 is configured with 'ip interface vlan <id>' followed by an address, separate from the VLAN port membership object.

Enable IP forwarding

ExtremeXOS requires 'enable ipforwarding vlan <name>' before a VLAN routes traffic; a default route is added with 'configure iproute add default'.

Show version command

'show version' displays the running software release and build; it is the first check when comparing behavior against release notes.

ExtremeCloud IQ onboarding path

A device reaches the cloud using DHCP option 43 or DNS discovery, obtains a management address, and is added to the tenant by serial number.

Configuration template overwrite

Local CLI changes made outside ExtremeCloud IQ can be overwritten by the next template push, so changes should be made in the management plane.

Client 360 view

An ExtremeCloud IQ monitoring page that aggregates a single client's connection history, RF quality, roaming events, and authentication results.

RBAC roles

ExtremeCloud IQ roles such as admin, operator, monitor, and installer restrict which users can view, configure, or onboard devices.

Firmware staging

Scheduling software upgrades from ExtremeCloud IQ by device group, so devices upgrade in controlled waves rather than all at once.

Backbone edge bridge

A BEB is a fabric node that hosts service access points and maps customer VLANs to I-SIDs, connecting users into Fabric Connect.

I-SID

A 24-bit service identifier used by Fabric Connect to map a customer service instance across the SPB backbone.

L3 VSN

A routed virtual service network in Fabric Connect that provides IP routing between fabric-attached subnets without traditional hop-by-hop routing.

VXLAN VTEP

A tunnel endpoint that encapsulates Layer 2 frames in UDP port 4789 for transport across a Layer 3 underlay.

EVPN control plane

A BGP-based control plane that distributes MAC and IP reachability for overlay networks, reducing unknown unicast flooding.

IS-IS adjacency check

'show isis adjacencies' confirms fabric neighbors are up; a missing adjacency points to area, system ID, or MTU mismatch.

802.1X roles

The supplicant is the client, the authenticator is the switch port, and the authentication server is RADIUS; EAP carries credentials.

DHCP snooping

A feature that binds client MAC and IP to a trusted port; dynamic ARP inspection and IP source guard use this binding database.

MACsec

Hop-by-hop Layer 2 encryption on supported links; both ends must agree on keys and cipher suites before traffic is protected.

Show tech-support

A diagnostic bundle collecting configuration, logs, and interface state; it should be gathered before opening a support case.
