Basic Switch Configuration Cisco Sg500 two switches

sanjay tripu · ‎06-30-2016

Hi ,

We have to configure two Cisco SG500 (48 port and 24 Port) switches using basic switching configuration without VLAN setup. We also have DHCP server on windows 2008 R2 64 bit OS , we have to define exceptions for few IP addresses and others should get them assigned from DHCP server. We have also Sonicwall NSA 2600 device to be connected to the switch. Both the swiches are little distance apart so that we can use ethernet cable to stack it or not. Please throw some light on the same.

End devices connected to the switch includes workstations, servers, Sonicwall, EMC VNXe box, Polycom IP Phones etc.,

Its a small network of 20 workstations.

Please help us design this so that we can implement it practically.

We are particular of not using VLANs and want the network to be simple.

Please help us.

Thanks

Sanjay

If you want IP phones and data you will want at least 2 VLANs (data and voice). This is still simple.

If it was me (without truly knowing your end goal) I would use the 48 port as an access switch and have the 24 port as a backup. Set up a port channel with 2 interfaces on both switches and make this port channel a trunk with data + voice VLAN. (you can also split the load if the location doesn't allow my idea - i.e. 10 users on 1 switch and 10 on the other)

Then on each used interface do a:

switch mode access

switch access vlan (number of data vlan)

switch voice vlan (number of voice vlan)

Do the necessary on your DHCP server (a pool for each VLAN), create a loopback address on each switch in the data VLAN and exclude this from the pool (trust me - makes configuration/troubleshooting/life much easier).

If you have Cisco's Packet Tracer I would recommend playing around with the style of set-up I have described and see how it works.

Can you also please let us know about configuring default static route to SonicWall LAN interface in the switch so that all the traffic passes to Sonicwall for WAN access (Internet).

For example:-

ip route 0.0.0.0 0.0.0.0 192.168.10.14 (Being LAN interface of Sonicwall).

Thanks

Hi Sanjay

You could set that as the default gateway on the DHCP server settings. Alternatively, like you said you could enable IP routing on the switch and then type the command you have already stated.

Hi,

I am attaching the network diagram for your perusal. Please go through it and let me know for any changes.

Polycom phones connected to cisco catalyst SG300 is managed by the vendor.

Please provide me the setup after going through the diagram.

Thanks

Sanjay
