Port-channel disoblige

[rj.kapildev]

Hi Folks,

We have a trouble in port-channel for an interface with point-point link, assigning ip to that interface possibly can make a ping,, whereas bringing the same interface to port channel assigning those same IP and try pinging to each other, unfortunately can't ping.

switch 1#

interface Ethernet2/20

  speed 1000

  duplex full

  bandwidth 1000000

  udld disable

  channel-group 2

  no shutdown

switch 2#

interface Ethernet2/37

  speed 1000

  duplex full

  bandwidth 1000000

  channel-group 2

  no shutdown

switch 1#

Command: show running-config interface port-channel2

Time: Fri Dec 27 09:49:3 2013

version 6.0(1)

interface port-channel2

  speed 1000

  duplex full

  ip address 1.2.3.1/30  --> altered ip

switch 2#

Command: show running-config interface port-channel2

Time: Fri Dec 27 09:50:48 2013

version 6.2(2)

interface port-channel2

  speed 1000

  duplex full

  ip address 1.2.3.2/30 --> altered ip

Please review and suggest us some valuable recommendation to overcome this issue.

What switch is this? Generally, to create a L3 etherchannel, you'll need to configure "no switchport" on the physical interfaces before you can use an address on the port channel interface.

I am assuming this is a Nexus switch of some flavor. To create a L3 etherchannel, create the port channel interface first, then add the physical interfaces to the port channel.
