Installation Guide

• To enter a prex number for a network mask, enter a forward slash (/) and the number of bits in the mask immediately after the
IP address. For example, enter "209.157.22.99/24" for an IP address that has a network mask with 24 signicant ("mask")
bits.
Assigning an IP address to a management interface
Instead of assigning a global IP address to the device for system management purposes, you now assign an IP address to the
management interface. The IP address is assigned to the active management module port. If the active management module becomes
unavailable and the redundant module becomes the active module, the IP address is assigned to the new active management module
port.
For example, to assign the IP address 10.0.1.1 to the management interface, do the following.
1. At the opening CLI prompt, enter enable.
device> enable
2. Enter the following command at the Privileged EXEC level prompt (for example, device# ), then press Enter. This command
erases the factory test conguration if still present.
device# erase startup-config
CAUTION
Use the erase startup-cong command only for new systems. If you enter this command on a system you have
already congured, the command erases the conguration. If you accidentally do erase the conguration on a
congured system, enter the write memory command to save the running conguration to the startup-cong le.
3. Access the conguration level of the CLI by entering the following command.
device# configure terminal
device(config)#
4. Congure the IP address and mask for the management interface by entering the following commands.
device(config)# interface management 1
device(config-if-mgmt-1)# ip address 10.0.1.1 255.255.255.0
Syntax: enable [ password ]
Syntax:
congure terminal
Syntax: interface management 1
Syntax: [no] ip address ip-addrip-mask
or
Syntax: [no] ip address ip-addr/mask-bits
Assigning an IP address to an interface, virtual interface, or loopback
As you have done with other devices, you must assign an IP address to each interface and virtual interface over which user packets are
routed. You can also assign an IP address to a loopback interface, which is generally used for testing and diagnostic purposes.
You must use the serial connection to assign the rst IP address. For subsequent addresses, you also can use the CLI through Telnet.
You can use Extreme Network Advisor to assign IP addresses to virtual routing interfaces only.
By default, you can congure up to 24 IP interfaces on each interface, virtual interface, and loopback interface.
