What relation between the two physical interface in Nexus7000 Fex?

[wfqk]

Hi, The Nexus7000 has two below interface configuration, which are all connected to FW1. 141 is one of Fex. The interface Ethernet6/4 should be one of ports of line card. I am not sure what is relation between the two interface. This two interfaces are separate physical interface, or only one interface? Any expert can give some suggestion? Thank you



interface Ethernet6/4
  description FW1
  switchport
  switchport mode trunk
  switchport trunk allowed vlan 3,19
  spanning-tree port type edge trunk
  udld aggressive
  no shutdown

interface Ethernet141/1/6
  description FW1
  switchport
  switchport mode trunk
  switchport trunk native vlan 99
  switchport trunk allowed vlan 3,19
  spanning-tree port type edge trunk
  spanning-tree guard root
  speed 10000
  duplex full

Those two are two separate physical interfaces for sure. i only see a difference from the configuration perspective where in the FEX port has the native vlan set to 99 and has root guard enabled.

The best thing would be to physically check the FW or Nexus on where these two connections are going (unless there is some cabling information available with you)

Thank you for your reply. The command "show ip arp" should be helpful to the issue, but the command cannot show any thing in the Nexus7k.

Rather than the show ip arp, check out the command show mac address-table <int>. That might provide the set of mac addresses learnt over the link.

show mac address-table can show mac address in interface Ethernet6/4, but interface Ethernet141/1/6 has no output.

Interface Ethernet141/1/6 is the fex interfac e could you please check what is connected onto this port?

show int E141/1/6 ?

[wfqk]

it shows it is down. Thank you

[InayathUlla Sharieff]

There you go..If it is down then looks to be nothing connected to the same :-)

[wfqk]
