ExtremeXOS Feature Compatibility with V400 Virtual Port Extenders

ExtremeXOS Feature Status
ACLs
Ingress (first and second stage) and egress ACLs are supported with the following limitations:
  • Ingress ACLs applied to a list of extended ports results in one hardware rule per extended port. This is the same behavior as regular ports when counters and/or meters are used.
  • Egress ACLs applied to an egress port do NOT match L2 flood traffic, but egress ACLs applied to VLANs do.
  • Ingress ACLs with Replace-ethernet-destination-address action, replace-ethernet-source-address, and replace-vlan-id actions are not supported when packets are egressing extended ports.
  • L3/L4 match criteria are not available in the same egress ACL key as an extended port match.
  • ACL byte counters include an extra 8 bytes per packet (Ethertype + Etag) for the added encapsulation.
  • Egress ACLs applied to extended port LAGs are not supported. Use egress ACLs bound to VLANs/any instead.
Note: When installing ACL rules bound to a set of ports, rules are replicated for each port if there are ACL counters and counter compression is not enabled or if the ports are extended ports.
Note: You can consume an excessive number of ACLs if you bind them to each individual (extended) port in cases where you have many extended ports. To avoid this, consider policy (role-based assignments per user) for access-control (see Policy Roles), ACLs bound to VLANs, wildcarded applications (see Configuring the ACL Rule on the Interface ), or two-stage ACLs (see Two-Stage ACL).
BFD Supported, except on extended ports.
CFM Supported, except on extended ports.
Diffserv examination Supported.
Disable slot Not supported.
Note: You can take a BPE slot offline by disabling the corresponding cascade port(s).
Dot1p examination Disabled by default on extended ports; enabled by default on controlling bridge cascade ports. Use cascade port Dot1p examination for extended port traffic to conserve ACL hardware resources.
EAPS Supported, except that EAPS ring ports cannot be extended ports.
EDP/LLDP/CDP Supported.
Note: BPEs will not appear as EDP neighbors.
EEE Supported.
ELSM Not supported.
ERPS Supported, except that ERPS ring ports cannot be extended ports.
ESRP Not supported.
FDB
FDB: Limit learning Supported.
FDB: MAC lockdown Supported.
FDB: Static and blackhole entries Supported, except that multi-port unicast FDBs entries are not supported.
Flood rate-limit Not supported on extended ports.
HcLAG Not supported.
Identity Management Identity Management should not be enabled on cascade ports.
L2 PBR Not supported.
FDB: multi-port unicast entries Not supported.
L3
L3: PBR Supported.
L3: Gateway routers Gateway router connected to extended port LAGs is not supported.
L3: IP unicast forwarding Maximum gateways (using configure iproute sharing max-gateways max_gateways ) must be greater than or equal to the number of active extended LAG members.
L3: Routing protocols

Supported on CB; not supported on extended ports.

L3 Tunnels

Supported on CB ports.

Not supported on extended ports.

LAG: LACP

Supported.

The default and only supported algorithm on extended port LAGs is "custom."

V400 Virtual Port Extender LEDs Supported. For information about the location of BPE LEDs, see the VPEX Quick Reference Guide.
Mirroring

Mirroring extended ports is supported.

Mirroring to extended ports is supported.

Mirroring to BPE cascade ports is not supported.

Limitations: Only known traffic to extended ports can be egress mirrored.

MLAG Supported on cascade ports; not supported on extended ports.
MPLS/VPLS Not supported.
Multicast
Multicast: IGMP Supported.
Multicast: MVR Supported.
Multicast: PIM Supported.
Multicast: PIM Snooping Supported.
MVRP Supported.
Netlogin Dot1X and MAC Auth supported, and supported with MLAG.
Not supported:
  • Multi-supplicant (MAC-based VLANs) without ONEPolicy.
  • Port restart option.
WebAuth is not supported with MLAG.
Node Alias Supported.
OnePolicy
Basic policy supported:
  • Policy scale (number of users, roles, rules) same as CB.
  • LAG rules not supported on extended ports with tci-overwrite.
  • Per-port, policy-driven, ingress rate limiting is not supported on extended ports.
PoE Supported on select BPE models. See Supported Bridge Port Extender Models.
Ports
Ports: Flooding Disabling flooding is supported.
Ports: Jumbo frame Enabling/disabling jumbo support on extended ports is supported; cascade-ports default to jumbo enabled.
Ports: Learning Disabling/enabling learning supported.
PVLAN Not supported.
QoS
Supported:
  • 8 queues per extended port.
  • Peak-rate supported per qosprofile per extended port.
  • CBS is 32 Kbytes.
  • Scheduling algorithms WDRR and strict priority.
  • Egress per-port rate limit per extended port.
Not supported:
  • Committed-rate per qosprofile per extended port
Note: Dot1p examination is enabled by default on cascade ports, but disabled by default on extended ports.
Restart port Not supported on extended ports. Use disable/enable port commands.
sFlow Supported: sFlow hardware sampling on Extended Edge Switching extended ports is provided by the underlying Extended Edge Switching cascade port hardware. As such, the configured sample rate is programmed on the cascade port and is provided in aggregate to all subtended sFlow-enabled Extended Edge Switching extended ports.
Software-redundant ports Supported.
STP Supported, primarily for edge loop detection (edge guard); supported with MLAG redundancy for RSTP and MSTP protocol modes.
VLAN
VLAN:Membership

Supported; users specify VLAN membership using <slot>:<port> notation; protocol VLANs not supported.

VLAN: statistics Supported on extended ports.
Note: VLAN flood traffic is not counted in the transmit counters; displayed counts include an additional 8 bytes for the Ethertype + E-tag encapsulation.
VMAN/CEP Not supported.
VMT/XNV Not supported.
VRRP Supported.
VXLAN Not supported.
