Installing Software When a Firewall Exists ERX Edge Routers
9Install the software release file to the system space on the ERX system.
10Save the current configuration.
11Reboot the system.
Task 1: Obtain the Required Information
Before you install the software, obtain the following information:
•The password (if one is configured) that allows you to access Privileged Exec mode on the ERX system
•The IP address of the network host
•The IP address of the ERX system
•The IP address of the next hop to reach the destination network (for example, a gateway)
•The login name and password for the vty line
•The procedure for mounting a CD on the network host
Task 2: Access Privileged Exec Mode
To access this mode via the CLI:
1Issue the enable command.
host1>enable
2Type the password if the system prompts you.
Task 3: Configure IP on an Interface
Typically, you configure IP on the Fast Ethernet interface of the SRP module. To configure IP on an interface:
1Determine the slot number of the module.
host1#show version
2Determine the port number of the module.
3Determine whether the interface already has an IP address.
host1#show ip interface fastEthernet 6/0
Note: If an IP interface is not configured, you see the message “Invalid interface.”
If the interface already has an IP address, go to step 5. Otherwise, proceed with step 4.
