Connect EVLANs Across SEFOS1 and SEFOS2

The interconnect between the two switches can be a regular port or an 802.3ad link aggregation port. In this example, a LAG port is used.

This task shows how to create a LAG port between the two NEMs and assign it as inter-switch trunk port.

  1. On SEFOS1, create a LAG consisting of ports 3, 4, 5, and 6.
    SEFOS# conf t 
SEFOS(config)# set port-channel enable 
SEFOS(config)# 
SEFOS(config)# interface port-channel 36 
SEFOS(config-if)# no shutdown 
SEFOS(config-if)# exit 
SEFOS(config)# 
SEFOS(config)# interface range extreme-ethernet 0/3-6 
SEFOS(config-if-range)# shutdown 
SEFOS(config-if-range)# channel-group 36 mode active 
SEFOS(config-if-range)# no shutdown 
SEFOS(config-if-range)# exit 
SEFOS(config)# 
SEFOS(config)# evlan 10 
SEFOS(config-evlan)# port add inter-switch po 36 
SEFOS(config-evlan)# evlan 600 solo port add inter-switch po 36 
SEFOS(config-evlan)# evlan 100 group port add inter-switch po 36 
SEFOS(config-evlan)# 
SEFOS(config-evlan)# end
  2. Show the EVLAN configuration.
    SEFOS# show evlan

  3. Create a a LAG on SEFOS2 and configure it as an inter-switch port for the EVLAN.
    SEFOS# conf t 
SEFOS(config)# set port-channel enable 
SEFOS(config)# 
SEFOS(config)# interface port-channel 36 
SEFOS(config-if)# no shutdown 
SEFOS(config-if)# exit 
SEFOS(config)# 
SEFOS(config)# interface range extreme-ethernet 0/3-6 
SEFOS(config-if-range)# shutdown 
SEFOS(config-if-range)# channel-group 36 mode active 
SEFOS(config-if-range)# no shutdown 
SEFOS(config-if-range)# exit 
SEFOS(config)# 
SEFOS(config)# evlan 10 
SEFOS(config-evlan)# port add inter-switch po 36 
SEFOS(config-evlan)# evlan 600 solo port add inter-switch po 36 
SEFOS(config-evlan)# evlan 100 group port add inter-switch po 36 
SEFOS(config-evlan)# exit 
SEFOS(config)# end 
SEFOS#
  4. Check the EVLAN configuration on SEFOS2.
    SEFOS# show evlan

    • On SEFOS2, port 2 is assigned host .149.

    # ping 38.38.38.70 
38.38.38.70 is alive
 
# ping 38.38.38.147
