Trunk Inter-Switch to EtherChannel

[kevinmjames]

Hello,

We have 2 4500X switches functioning as our iscsi network between storage arrays and vmware esx servers.  Currently the two switches just have a single trunk inter-switch connection between the two.  Our storage vendor is recommending we remove that and implement an EtherChannel.  Is there a way to do this without losing connection to the storage arrays.  And also enable jumbo frames on the EtherChannel.

Thanks

  Configure  "interface port-channel 1" with the same configuration as the existing trunk port. on both switches.

then add "channel-group 1 mode on" on both trunk interfaces

then configure the new ports on each switch, same as existing ports. do not enable the new ports until the configuration is complete.

RE Jumbo frames please see this link
