ExtremeXOS Feature Compatibility with V400 Port Extenders

ExtremeXOS Feature Compatibility with V400 Port Extenders shows which ExtremeXOS features are supported, or are not supported, or that have limitations when used with V400 Port Extenders.

ExtremeXOS Feature	Status
VLAN:Membership	Supported; users specify VLAN membership via <slot>:<port> notation; protocol VLANs not supported.
ACLs	Ingress (first and second stage) and egress ACLs are supported with the following limitations: Ingress ACL IPBM match criteria does not work, which results in increased ACL hardware utilization. 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. Egress ACLs that additionally match extended-ports are subject to qualifier restrictions on the controlling bridge—L3/L4 match criteria are not available in the same egress ACL key as the “DVP” (extended port) match. ACL byte counters include an extra 8 bytes per packet (Ethertype + Etag) for the added encapsulation.
CFM	Not supported.
Diffserv examination	Supported on CB; can also use cascade port DSCP.
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.
L2 PBR	Not supported.
L3
L3: PBR	Supported.
L3: Routing protocols	Supported on CB; not supported on extended ports.
LAG: LACP	Supported. The default and only supported algorithm on extended port LAGs is "custom."
Mirroring	Mirroring extended ports is supported. Mirroring to extended 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: IGMP	Supported.
Multicast: MVR	Supported.
Multicast: PIM	Supported on regular ports. Not supported on extended ports.
Multicast: PIM Snooping	Supported.
MVRP	Not supported.
Netlogin	Basic Dot1X, MACAuth supported; multi-supplicant (MAC-based VLANs) and WebAuth not supported.
OnePolicy	Basic policy supported: Policy scale (number of users, roles, rules) same as CB. LAG rules not supported on extended ports. 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. No egress port-based rate limiting on extended-ports. Peak-rate supported per qosprofile per extended port. Committed-rate not supported. CBS is 32 Kbytes. Scheduling algorithms WRR and strict priority supported.
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); not supported with MLAG redundancy.
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.
