ExtremeXOS Feature Compatibility with V400 Virtual Port Extenders

ExtremeXOS Feature Compatibility with V400 Virtual Port Extenders shows which ExtremeXOS features are supported, or are not supported, or that have limitations when used 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).
CFM	Not supported.
Diffserv examination	Supported.
Disable slot	Not supported. Note: You can take a BPE slot offline by disabling the corresponding cascade port(s).
Dot1p examination	Supported.
EAPS	Supported.
EDP/LLDP/CDP	Supported.
ELSM	Not supported.
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 ports 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 and BPE cascade ports is not supported. Limitations: Egress mirroring on extended port does not work for flooded traffic. Only known traffic to extended ports can be egress mirrored.
MLAG	Supported on cascaded ports; not supported on extended ports.
MPLS/VPLS	Not supported.
Multicast
Multicast: General	The scaling of multicast cache on a Extended Edge Switching topology depends on the number of BPE ports and the number of VLANs that have extended ports because the BPE ports and VLANs consume hardware resources used by multicast cache.
Multicast: IGMP	Supported.
Multicast: MVR	Supported.
Multicast: PIM	Supported.
Multicast: PIM Snooping	Supported.
MVRP	Not 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.
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 rate limiting not supported on extended ports.
PoE	Supported on select BPE models. See Supported Bridge Port Extender Models.
Ports
Ports: Flooding	Disabling flooding not 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. Committed-rate not supported. CBS is 32 Kbytes. Scheduling algorithms WDRR and strict priority supported. Not supported: Committed-rate.
Restart port	Not supported on extended ports. Use disable/enable port commands.
Software-redundant ports	Supported.
STP	Supported, primarily for edge loop detection (edge guard); supported with MLAG redundancy.
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.
