Port Security Switches

Hi,

I have cluster of servers for redundancy.

I want to connect these servers to 2 switches for further redundancy.

If I configure port security on these switches, can these switches work with the servers?

The servers may be using virtual IP address or virtual MAC address or both.

Must these switches be layer 2 switch or layer 3 switch?

Must I configure vlans on the switches?

Anything else that I need to know in configuring the switches in order to make the switches work with HA or cluster of servers?

Pls advice

Thank you

Rachel

Re: Port Security Switches

Hi Rachel,

Setting up port security with regards to your clustered servers will take a baseline understanding of port security.

1. a switch learns mac addresses by reading the source mac address of frames transmitted into the port.

2. a first step would be to understand what source mac addresses are in play here.

3. port security is designed to allow only a give number of learned or statically defined mac addresses.

Layer2 or Layer3 swithcing and vlans that's a broad set of topics that would require more specifics to your network overall.

Be careful when dual homing servers to ensure they are not bridging, that could bring up some nasty issues with spanning-tree protocol.
