I would suggest you to configure HSRP between your core switches (3750's) than doing STACK. When you want load balance/sharing with HSRP then you need to configure multiple hsrp groups to do the job. See the below example config...
Switch-1 interface FastEthernet0/0 ip address 10.10.12.1 255.255.255.0 standby 1 preempt standby 1 ip 10.10.12.3 standby 1 priority 110 standby 2 preempt standby 2 ip 10.10.12.4
Switch-2 interface FastEthernet0/0 ip address 10.10.12.2 255.255.255.0 standby 1 preempt standby 1 ip 10.10.12.3 standby 2 preempt standby 2 ip 10.10.12.4 standby 2 priority 110
After you did the above config, you will have group 1 with Switch-1 active (10.10.12.3) and group 2 with Switch-2 active (10.10.12.4). Of course you will have to find a way to push to the clients the 2 gateways (10.10.12.3 and 10.10.12.4) or to configure them manually on your users machines, to really achieve the load balance feature with HSRP.
" firewall is in active standby mode.. but why we need to luk in the firewall HA stat?
so if i have one firewall.. cant we run hsrp for the core switches?
You can run HSRP on the L3 switches regardless of whether the FW's run in Active/Active or Active/Standby mode.
because the Active L3 switch will send the traffic to the vIP of the FW's and the FW's send the traffic back to the vIP of the HSRP. only thing if you are going to run active/active is to hardcode the static arp and mac address of FW vIP on the L3 switch.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
