Hi Upendra,
you can make of both the ports to run at the same time by achieving 2Gbps with the help of configuring etherchannelling.
here is the config.
interface gi 0/1
channel-group 1 mode on
interface gi 0/2
channel-group 1 mode on
by issuing this command automatically a virtual port will be created
interface port-channel 1
same command issue on the other side of the switch, by doing this, even if cable fails the other will take care automatically without any downtime.

Hi Upendra,
gone thru the diagram, did u configured any vlans on ur network? how any PC's are there on the network, this diagram which you have sent, definetly will create loop. what i would suggest is connect all the 2960 switches to 3750, so that 3750 switch becomes the core switch.
any thing else lemme know, so that i can suggest more.

yes
dear
we have 20 vlan on 3750(L3 switch).700 pcs in our network.as per my diagram i want configure failover.When one link is goes down my network follow another link
06-20-2007 03:56 AM
you thinking about only the link failure between the switches, but you should also consider what happens if the main switch itself fails(3750), so as suggested, configure etherchannel between the switches, also i would advice you to have additional 3750 & configure HSRP, make sure that you the current setup & point all you access switches to 3750.

We have 375012s-E and 375024Ts in stack.
I ordered new 24ts our planing is we connect this switch in stack.AS per diagram i want to configure failover mode for all switches.
06-20-2007 09:58 PM
k, what i would prefer is, stack all the 3750's, then connect all your 2960's with 2 cables, by creating etherchannel, like connecting 1 cable on 1 of the 3750 & the other on the other 3750 switches, bcoz stacking multiple 3750's will act as single switch virtually.
