Answers: Switch IP 1

By certskills November 21, 2015 12:05

Cisco Catalyst switches typically allow Telnet/SSH access as a matter of habit. For practice, check out the earlier lab exercise, create your own answer, and check your answer against this blog post.


Example 1: SW1 Config



On Cisco switches, VLAN 1 is the default VLAN for all interfaces in a switch. When you assign a IP address the VLAN 1 interface on the switch, that switch then uses that IP address to support its own IPv4 traffic, for instance, traffic like ping and Telnet packets.

To configure the IP address for the VLAN 1 interface, you first enter VLAN 1 configuration mode with the interface vlan 1 command. At that point, you configure the IP address and mask (with the ip address address mask command). Then you enable the VLAN interface with the no shutdown command.

Note that the VLAN 1 interface is not the same idea or configuration element as VLAN 1 itself. A switch’s VLAN 1 interface is that switch’s interface connected to the subnet that exists on VLAN 1.

Additionally, the global configuration command ip default-gateway ip-address gives the switch a default gateway to allow communication through a router to other subnets.
