Do you need VLAN support or just a routed interface ? -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Richard J. Sears Sent: Tuesday, July 27, 2004 10:23 PM To: Nanog Subject: COnfiguration Suggestion - Etherchannel Hey Everyone, I am building out a customer that needs more than 1000Mbps of sustained bandwidth. Because of the customer equipment, etherchannel was suggested as the means to do this (it is compatible with this customers equipment). I am running a 6509 with Dual SUP720's in IOS mode only (no cat software). It was pointed out that there are really two different ways to configure the switch - I guess my question is which is the best (lowest overhead, etc)? Hopefully someone out there has been down this road before. TIA Two methods: ! interface Port-channel2 no ip address switchport switchport access vlan 10 switchport mode access ! interface GigabitEthernet7/1 no ip address switchport switchport access vlan 10 switchport mode access channel-group 2 mode on ! interface GigabitEthernet8/1 no ip address switchport switchport access vlan 10 switchport mode access channel-group 2 mode on ! interface Vlan10 description Customer_Name ip address 192.168.0.1 255.255.0.0 no ip redirects no ip unreachables ! And then there is this way: ! interface Port-channel2 description Customer_Name ip address 192.168.0.1 255.255.0.0 no ip redirects no ip unreachables ! interface GigabitEthernet7/1 description Customer_Name EtherChannel Interface #1 no ip address channel-group 2 mode on ! interface GigabitEthernet8/1 description Customer_Name EtherChannel Interface #2 no ip address channel-group 2 mode on ! ****************************************** Richard J.
