Port-channel interface x Configuration ?

[Jasonlees]

Hi Guys,

I have one question on a configuration. I need a port channel for nfs like so:

interface range GigabitEthernet g/2/1/12 - 13
description filer interface e0a
switchport
switchport mode access
switchport nonegotiate
flowcontrol receive on

no cdp enable
spanning-tree guard loop
spanning-tree portfast
channel-group 1 mode on

As well I need a trunk between switches, using this command to set it up:

int range ge2/0/20 -21
channel-group 2 mode on

Is this the correct way to run configure the 2 port-channels and do I need separate one's?

1/ Yes, they need to be seperate.

2/ What's "nfs"? Does it support Cisco-proprietary link aggregation? If not, then the command is channel-group 1 mode active

since we on this subject, Can some body explain ether-channel
from using the on switch or desire mode.

i have two 2970's using port-channeling with the on mode. should i be using desirable? whats the difference . if one link goes bad does that mean my channel is broken? I want to make sure I'm redundant

the "on" switch essentially disables the use of either pagp or lacp to negotiate the etherchannel. auto/desirable are used for pagp negotiation and active/passive are for lacp negotiation. the fact that you are configuring a manual or "static" etherchannel is actually a bit better since no negotiation needs to take place with the swtich on the other side; you just need to make sure that both sides are set to "on" otherwise no etherchannel will form. if one link goes bad then you're still in business.

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

nfs is storage; the port-channel command worked and both are working.
