A technician configures a switch with these commands:SwitchA(config)# interface vlan 1SwitchA(config-if)# ip address 192.168.1.1 255.255.255.0SwitchA(config-if)# no shutdownWhat is the technician configuring?
The technician is configuring the VLAN 1 interface on the switch.
Firstly, the command “interface vlan 1” is used to enter the configuration mode for VLAN 1. VLANs (Virtual Local Area Networks) are used to logically segregate a network into smaller, isolated broadcast domains.
Then, the command “ip address 192.168.1.1 255.255.255.0” assigns an IP address 192.168.1.1 to the VLAN 1 interface, with a subnet mask of 255.255.255.0.
This means that any device connected to VLAN 1 can communicate with other devices in the same IP subnet range, from 192.168.1.1 to 192.168.1.254.
Finally, the “no shutdown” command is used to enable the VLAN 1 interface.
By default, interfaces on switches are in a shutdown state, and this command brings the VLAN 1 interface up, allowing it to send and receive network traffic.
