Confiuring VLAN and Etherchannel using Aruba 6000 with Cisco 3750 Switch

Networking

We were setting up an Aruba with a Cisco 3750 we are trying to allow trunking of VLANs to the aruba from the switch and also bonding both the NICs on the aruba to two ports on the cisco in an etherchannel to give us 2GB uplink.

Here’s how we did it, we didn’t need to set any speed settings on the cisco, but did on the Aruba end.

interface gigabitethernet  2/0

description "gig2/0"

trusted

trusted vlan 1-4094

speed 1000

duplex full

switchport mode trunk

no spanning-tree

interface gigabitethernet  2/1
