Connect XVLANs 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)# internal port-channel 36 
   SEFOS(config-if)# no shutdown 
   SEFOS(config-if)# exit 
   SEFOS(config)# 
   SEFOS(config)# internal 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)# xvlan 10 
   SEFOS(config-xvlan)# port add inter-switch po 36 
   SEFOS(config-xvlan)# xvlan 600 solo port add inter-switch po 36 
   SEFOS(config-xvlan)# xvlan 100 group port add inter-switch po 36 
   SEFOS(config-xvlan)# 
   SEFOS(config-xvlan)# end

2. Show the XVLAN configuration.

   SEFOS# show xvlan

3. Create a a LAG on SEFOS2 and configure it as an inter-switch port for the XVLAN.

   SEFOS# conf t 
   SEFOS(config)# set port-channel enable 
   SEFOS(config)# 
   SEFOS(config)# internal port-channel 36 
   SEFOS(config-if)# no shutdown 
   SEFOS(config-if)# exit 
   SEFOS(config)# 
   SEFOS(config)# internal 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)# xvlan 10 
   SEFOS(config-xvlan)# port add inter-switch po 36 
   SEFOS(config-xvlan)# xvlan 600 solo port add inter-switch po 36 
   SEFOS(config-xvlan)# xvlan 100 group port add inter-switch po 36 
   SEFOS(config-xvlan)# exit 
   SEFOS(config)# end 
   SEFOS# 

4. Check the XVLAN configuration on SEFOS2.

   SEFOS# show xvlan

   ---------------------------------------------------- 

5. Check the LAG port status.

   SEFOS# show etherchannel summary

   Port-channel Module Oper Status is enabled 
   Port-channel System Identifier is 00:14:4f:6c:56:0f

6. Ensure that the external hosts on SEFOS1 and SEFOS2 can be reached.

   [root@nsn173-139 ~]# ping 38.38.38.146 
    
   PING 38.38.38.146 (38.38.38.146) 56(84) bytes of data.

   64 bytes from 38.38.38.65: icmp_seq=2 ttl=64 time=0.192 ms

8. Ensure that the solitary-restricted port on SEFOS2 and the external port on SEFOS1 can communicate.

   nsn173-90:~ # ping 38.38.38.139 
    
   PING 38.38.38.139 (38.38.38.139) 56(84) bytes of data. 
   64 bytes from 38.38.38.139: icmp_seq=1 ttl=64 time=1.94 ms

9. Ensure that the solitary-restricted ports on SEFOS1 and SEFOS2 can communicate with each other.

   The hosts are expected to be unreachable.

   nsn173-90:~ # ping 38.38.38.147

   From 38.38.38.90 icmp_seq=1 Destination Host Unreachable 
   From 38.38.38.90 icmp_seq=2 Destination Host Unreachable 

10. Ensure that the group-restricted ports on SEFOS1 and SEFOS2 can communicate with each other.

    The hosts are expected to be reachable. On the restricted XVLAN 100, the following hosts are assigned:

    • On SEFOS1, port 2 is assigned host .147, port 15 is assigned host .70.

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

    # ping 38.38.38.70 
    38.38.38.70 is alive
     
    # ping 38.38.38.147
    38.38.38.147 is alive 
    # 

11. Show the host MAC addresses learned on the SEFOS1 and SEFOS2 switches.
    1. On SEFOS1, type.
