Hi,
Seen the docs that state the 4710 appliance uses neither PAGP nor LACP.
The snag I have now is that I have a 4710 connected to 2 x 3750X with one port in each. The switch ports must be LACP but the output of show etherchannel summary is:
2 Po2(SD) LACP Gi1/0/13(I) Gi2/0/13(I)
Is that normal? They are both in stand-alone mode.
many thanks

Hello Ali,
I am not sure about the expected behaviour when you configure LACP or PAgP with your ACE(not supported). As you understood it right, The ACE does not use either protocol. If you intend to configure Layer 2 EtherChannel bundles between an ACE and a Catalyst switch, all ports in the bundle must be statically assigned at both end.
Neither LACP or PAgP are supported on the 4710. For sure only 802.1q encapsulation is supported (no ISL).
This info is directly from the routing and bridging guide, here is the etherchannel configuration specifically:

Thanks Ricky,
that was the doc i was looking at too. so it seems that the ACE ports are in a channel-group but the switch ports operate as stand alone
hmmm...

Hi Ali,
I just checked this in lab. it seems that when you use LACP for bundling, the ports seems to be in standalone and not getting bundled up, but when i just turn the active into "ON" it just bundles up properly.
Thanks,

Am i missing something? "ON" is for PAGP is it not? when i try to change it i get:
%With PAgP enabled, all ports in the Channel should belong to the same switch
Command rejected (Port-channel2, Gi1/0/13): Invalid etherchnl mode %
this is what the config looks like on the switch. i didn't include the ACE as there's not a great deal to it:
interface Port-channel2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan AAA
switchport mode trunk
interface GigabitEthernet1/0/13
switchport trunk encapsulation dot1q
switchport trunk allowed vlan AAA
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-protocol lacp
channel-group 2 mode active
interface GigabitEthernet2/0/13
switchport trunk encapsulation dot1q
switchport trunk allowed vlan AAA
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-protocol lacp
channel-group 2 mode active

Hi Ali,
PAgP is auto/desirable, LACP is active/passive and "ON" is a static assignment,
interface Port-channel2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan AAA----> Should be VLAN number
switchport mode trunk
interface GigabitEthernet1/0/13
switchport trunk encapsulation dot1q
switchport trunk allowed vlan AAA------> Should be VLAN number
switchport mode trunk
speed 1000
duplex full
channel-group 2 mode on
interface GigabitEthernet2/0/13
switchport trunk encapsulation dot1q
switchport trunk allowed vlan AAA------> Should be VLAN number
switchport mode trunk
speed 1000
duplex full
channel-group 2 mode on
Let me know if the above config works..
Thanks,
Ricky Micky
