connecting 3560 sw

hi!  i'm trying to connect 2x L3 3560 sw together to run hsrp. What's the different of connecting both switch together using etherchannel through the sfp (uplink port) vs the copper GigaEthernet Ports? Will there be lots of different in term of performance and etc?

Hi Dave,

     There are 2 things in your question. First,we use HSRP for gateway redundancy. You can think of using HSRP on  2x3560 as Active/Standby mode. You also can design MHSRP for users. Second,Etherchannel is described in term of increasing bandwidth of links and providing fault torerance for links. You can use both together. It depends on your design.

hi! i understand about the hsrp and etherchannel config, but i'm not too sure what's the different of using the RJ45 GigaEthernet port vs the Fiber Uplink port to establish the trunk channel? Will there be any concern for using GigaEthernet port? I do not wish to  purchase the sfp module. Thanks.

Hi,


We can use both Ethernet and Fiber for uplink and run HSRP.
Actually the Ethernet uplink used widley becuase by default the ports available and no need to buy any SFP modules and it is easy to manage and cost effective.

When you wnat uplink the switches with fiber then you need to buy extra SFP modules and also not that much easy to manage.

Please rate the helpfull posts.

Hi,

   You can use GigaEthernet ports connecting between C3560 if your cable length is not longer than 100 meter. No need to use SFP modules and fiber cables. However,it depends on your design.
