Ethernet Segment Identifier (ESI) is a 10-octet identifier value that denotes an Ethernet Segment. It is used to discover and group the various interfaces of a multi-homed client. This command is used to manually assign Ethernet Segment Identifier (ESI) value to the segment. The same local port-channel id should be used by the multi-homed leaf peers on links connected to the same host.
Ethernet Segment mode within Ethernet and Port-channel interface modes.
Ethernet Segment Identifier is a 10-octet identifier value that denotes an Ethernet Segment. It is used to discover and group the various interfaces of a multi-homed client.
The [no] format of the command removes the Ethernet Segment Identifier value mapped to ethernet segment of the selected interface.
The following example shows the configuration of a leaf node with connections to two different multi-homed hosts.
SLX(config)# interface Ethernet 0/1 SLX(conf-if-eth-0/1)#ethernet-segment SLX(conf-if-eth-0/1-es)# esi 00:11:22:33:44:55:66:77:88:99 SLX(config)# interface Port-channel 1 SLX(config-Port-channel-1)# ethernet-segment SLX(config-Port-channel-1-es)# esi 00:11:11:22:22:33:33:44:44:55
