I have some questions about routing and switching design.
I have old Cisco network (Catalyst 4006, ...)
With several end point connected with fiber .
Today i have some network loop (spanning tree is in use).
I have some questions about change in my network.
1) Is it better to change the Catalyst 4006 with 4700 serie, or install 3750 Catalyst switch (using Stackwise techno). ?
2) Is it better to use Etherchannel to secure fiber link rather than spanning tree loop ?
3) To secure my gateway is it possible to use HSRP with 3750. I have one gateway per vlans (10 Vlans).
Thanks for your recommandations
