Configuring L3 switch
Posted on 2013-12-19
We have an existing Cisco SG300-28 switch in L3 mode. Because we needed more ports, we are buying another switch -- same exact model.
I will be trunking them together, and allowing some of our ESXi server to do NIC Teaming across both switches.
How do I configure the VLAN IPs on the 2nd switch?
For example, below is the list of IPs and associated VLANs on switch 1:
VLAN 1000 - 10.10.0.1 (255.255.255.0)
VLAN 1020 - 10.20.0.1 (255.255.255.0)
VLAN 1030 - 10.30.0.1 (255.255.255.0)
VLAN 2 - 10.0.15.249 (255.255.255.248) -- connects to main firewall/router LAN port.
On switch 2, what IP/subnet mask should I assign to the above mentioned VLANs.
**NOTE: Only Switch 1 connects to the firewall. This means that any traffic on switch 2 that is headed outside our network (internet), needs to go through Switch 1 in order to hit the firewall.
