3750 Stackwise vs. HSRP 1

[laruecl]

On our network, we have 2 3750's connected via stackwise cable. The question has come up and I need to know, does anyone know of an advantage to using HSRP instead?

Not sure what you mean hsrp is used for creating reduncancy across 2 or more links say up to a core dist. routers whereas stackwise is basically a connecting cable allowing you to manage 2 or more 3750's with 1 ip address for the whole stack , really 2 different things. Technically if you have 2 different uplink connections 1 to each 3750 then you do have redundancy also because if you lose 1 switch the other switch has the complete configuration also so you shouldn't lose connectivity.

thanks vipergg, I probably should have included more info in my post.
Here is my setup
I have 2 3750's connected via stack cable. I have 4 redundant uplinks, 4 connecting to one switch and 4 connecting to the other. I believe that is offering good redundancy. I was told without HSRP, I do not have reliable redundancy. So I am wondering what HSRP would offer here that I do not already have. I know I would lose 2 gig port running HSRP but I am wondering if there is a benefit that I am overlooking.

I guess the question do the uplinks all go to the same switch ? If so then you have a single point of failure for your uplinks . Basically hsrp would give you redundant "routing" paths usually to 2 separate dist. boxes . If all your links go to the same box you don't have "routing redundancy .

then it sounds like I am good. Uplinks are duplicated on both switches which provides our redundancy. Thank you
