Re: hp 2910al switch trunking and basic understanding
3. How would I configure Switch-2 to talk with Switch-1 subnet.
you need a router to enable communication between different subnets.
when both subnets are used on different vlans, this router must have two interfaces, one in each vlan/subnet.
this can be done by the firewall, or by one of the switches
If you use switch-1 for this, switch-2 does not do any routing and only needs an ip-adress for management.
you need to make switch-2's vlan avalable on switch-1
you do this by configuring the vlans on the ports that connect the switches
(untagged/tagged or both tagged)
lets say port 24 both switches
>>>
vlan1
untagged 24
vlan2
tagged 24
<<<
you configure the ip-adress not on the interface, but on the vlan.
switch-1
>>>
vlan1
ip adress 180.10.1.1/24
vlan2
ip adress 180.10.2.1/24
ip helper
<<<
switch-2
>>>
vlan1
ip adress 180.10.1.2/24
vlan2
ip adress 180.10.2.2/24 (not really necessary)
<<<
and enable routing on switch-1
>>>
ip routing
ip route 0.0.0.0 0.0.0.0
<<<
+ firewall will have a return route for 180.2.10.0/24 network. to switch-1

Re: hp 2910al switch trunking and basic understanding
Hi Deeps
Doesn't matter. The rules for trunking (Link Aggregtion) are simple.
- the members of the trunk must be same speed/duplex - no trunking 100Mb/s port with a Gig port
- the members of the trunk must be same media type - no trunking Fiber with Copper
- the members of the trunk must be co-terminating - no connecting Switch A port 1 to Switch B and Switch A port 2 to Switch C
I assume we're talking about normal Link Aggregation, not Distributed Trunking. If you're doing DT the third rule doesn't exist.
HTH,
