I am trying to configure ether channel between a cisco ws-c2960s-24ts-l switch and a linux server. I found out that i needed to use lacp as it supports interoperability between different types of hosts. i followed cisco's guide for forming ether channel. However when i do the configuration the ethernet goes down and the device becomes unpingable.

On the Linux side, the configuration looks like this:

Code: 
cat /etc/modprobe.d/bond.conf 
alias bond0 bonding  

cat /etc/sysconfig/network-scripts/ifcfg-bond0 
DEVICE=bond0
ONBOOT=yes
USERCTL=no
BOOTPROTO=none
NM_CONTROLLED="no"
IPADDR=10.76.161.135
PREFIX=21
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System bond0"
BONDING_OPTS="mode=4 miimon=100 lacp_rate=1"

cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE="eth1"
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
 
This is a quite specific network/linux question not really related to DA. Maybe someone who reads this here happens to know how to help you out, but I wouldn't bet on it. You can probably get more help on other forums more specialized in this.
