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 Compatibility with V400 Virtual Port Extenders
ExtremeXOS Feature | Status |
---|---|
ACLs |
Ingress (first and second stage) and egress ACLs are supported with the
following limitations:
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 | 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 | 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. |
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 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 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 | Not supported. |
Netlogin | Dot1X and MAC Auth supported, and supported with
MLAG. Not supported:
WebAuth is not supported with MLAG.
|
Node Alias | Supported. |
OnePolicy |
Basic policy supported:
|
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:
Not supported:
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 | Supported. |
