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.

Table 1. 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).
AVB	Not supported.
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.
Fabric Attach	ExtremeXOS Fabric Attach (FA) supports FA servers and FA Proxies to be Extended Edge Switching controlling bridge (CB) nodes connected with bridge port extenders (BPEs) in two different topologies: Single-arm This command is available on all Universal switches supported in this document. ring—see Single-ARM MLAG Ring Topology Configuration Examples. Cross-connect MLAG—see Cross-Connect MLAG Topology Configuration Examples.
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 V400 Virtual Port Extender Quick Reference Guide.
Mirroring	Mirroring extended ports is supported. Mirroring to extended ports is supported on all Universal platforms. Ingress mirroring of an extended port will include an 802.1BR E-tag. Note: Workaround: You can avoid this 802.1BR E-tag by doing the following: Run the command: enable mirroring to port-list 1:1 loopback 1:2. Where in this example, port 1:2 is not connected to anything. Run the command: configure mirroring add port 104:1. Where in this example, port 104:1 is the extended port. 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. Not supported on cascade ports when in stacking mode.
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. Trusted ports. 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. ExtremeSwitching 5420 and 5520 series switches as CBs do not support tci-overwrite.
PoE	Supported on select BPE models. See Supported Bridge Port Extender Models. Operator limit configuration is not supported on cascade ports.
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. The max-frame-size on V400 is enforced only on ingress, and not on egress.
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. Note: When using hyrbid QoS scheduling, strict-priority queues must be the highest number queues.
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	Supported for tagged and untagged tenant VLANs on extended ports, except for ExtremeSwitching 5420 and 5520 series switches. Extended port LAG in VXLAN is not supported. Extended ports cannot be in VXLAN network VLANs. Extended ports cannot participate in RIOT configurations. Ring is not supported for VXLAN extended ports. Optimized IP Multicast Replication is not supported for VXLAN extended ports.
