Is it possible to use a Cisco 2950 switch as a DHCP relay? If so, how can I? I've configured a C172x router but the switch seems different.
Commands for DHCP functionality
| ||To enter global configuration mode.|
| ||To enable DHCP snooping globally.|
| ||To enable DHCP snooping on a VLAN or range of VLANs. You can specify a single VLAN identified by VLAN ID.|
| ||To enable the switch to insert and remove DHCP relay information (option-82 field) in forwarded DHCP request messages to the DHCP server. This is enabled by default.|
| ||To enter interface configuration mode, and specify the interface to be configured.|
| ||This is an optional command. It configures the interface as trusted or un-trusted. The default is un-trusted.|
| ||This is an optional command. It configures the number of DHCP packets per second than an interface can receive. The range you can specify for [rate] is 1 to 4294967294. The default is no rate limit configured.|
[ ] expects arguments to be given like VLAN-ID or rate limit. The first five commands should be enough to configure DHCP relay. The other two give the functionality more granularities.
