Configuring the IP Address
Each switch must be assigned its own in-band IP Address, which is used for communication with an SNMP network
manager or other TCP/IP applications. The Switch's default IP address is 10.90.90.90 with a subnet mask of
255.0.0.0. You can change the IP address of the Switch to meet the specification of your networking address scheme.
The IP address of the Switch must be configured before it can be managed, by the user, via the Web UI.
An example to change the IP address of the Switch to '10.50.50.50', using a subnet mask of '255.0.0.0':
Switch>enable
Switch#configure terminal
Switch(config)#interface vlan 1
Switch(config-if)#ip address 10.50.50.50 255.0.0.0
Switch(config-if)#
In the above example,
1. We accessed the Privileged EXEC Mode by entering the command enable.
2. Then we entered the Global Configuration Mode by entering the command, configure terminal.
3. Then we entered the VLAN Configuration Mode of the default VLAN, which is VLAN 1, by entering the
command, interface vlan 1.
4. Then we changed the IP address of the Switch to 10.50.50.50 and the subnet mask to 255.0.0.0 by entering
the command ip address 10.50.50.50 255.0.0.0.
The Switch can now be accessed and configured through Telnet or the Web UI. The Switch's IP address can also
automatically be obtained by using the DHCP protocol.
Connecting to the MGMT Port
The front panel of the Switch features an Out-Of-Band (OOB) RJ45 MGMT port which can be used to connect to a
computer using a standard Ethernet cable. A web browser or Telnet client can be used to connect to the Switch using
the MGMT port.
To use the MGMT port, connect one end of an Ethernet cable to a computer and the other end to the Switch. The
default IP address of the MGMT port is 192.168.0.1 and the subnet mask is 255.255.255.0. Make sure that the
computer being used for the switch management has a non-conflicting IP address in the 192.168.0.0/24 network.
To view the IP settings of the MGMT port, use the following command:
Switch#show ip interface mgmt 0
mgmt_ipif 0 is enabled, Link status is up
IP address is 192.168.0.1/24
Gateway is 0.0.0.0
Switch#
The IP settings or enabled status of the MGMT port can be changed through the console port. For example, to change
the IP address of the MGMT port, use the following commands:
Switch#configure terminal
Switch(config)#interface mgmt 0
Switch(config-if)#ip address 192.168.1.1 255.255.255.0
Switch(config-if)#
