Cisco 2950G Spanning Port

Can anyone tell me if I can use a single IDS attached to the spanning port to manage / monitor all ports on that switch.

Yes, you can use a single IDS attached to the spanning port to manage all the ports on the switch.

Yes, you could. Here is a good link on monitoring ports, including a configuration for multiple ports being monitored:

Here is a snippet of the configuration example:

Switch(config)# no monitor session 1

Switch(config)# monitor session 1 source interface fastEthernet0/10 tx

Switch(config)# monitor session 1 source interface fastEthernet0/2 rx

Switch(config)# monitor session 1 source interface fastEthernet0/3 rx

Switch(config)# monitor session 1 source interface port-channel 102 rx

Switch(config)# monitor session 1 destination remote vlan 901 reflector-port fastEthernet0/1
