Setting the Clock

Configuring the XSR Name and User Information

+The XSR waits one minute for the PPPoE connection to come up.

Phase 4 - ADSL - IP is connected on 0/35, prepare to load startup config

+The XSR starts downloading the startup-file.

Phase 6 - ATM/ADSL - retrieving file 0000019876543210-confg from tftp server 25 5.255.255.255

+The startup-config name is the serial number of the XSR.

Phase 7 - preparing node to execute startup-config

Configuring the XSR Name and User Information

1.At the CLI prompt, enter enable to acquire Privileged EXEC mode.

2.Enter configure to acquire Global mode.

3.Enter hostname <your XSR designation>.

4.Enter username <name> <privilege level> password <cleartext secret> <0 5> <password>.

5.Enter banner login <your welcome text> to add a user login banner. Remember to save your configuration after all edits.

Setting User Name, Privilege and Password

The value <name> is the user’s designation - for sake of clarity, often set as the name of the facility or site the XSR connects to. The value <privilege level> (0-15) prioritizes this user in terms of configuration rights with 15 as the highest and 0 the lowest (default). When you create a new user you can decide which privilege that user will have (if you are admin). For example, a user with privilege 7 will be allowed to execute only commands with privilege levels between 0 and 7.

Default privilege levels are defined for all commands and the admin user and are listed in the XSR CLI Reference Guide under the privilege command. You can change a command’s default privilege by entering: privilege <configuration_mode> level <0-15> <command command_group>.

The value <cleartext secret> can be sent in the clear or encrypted with a 0 (the input password is not expected to be unencrypted so the XSR will encrypt it) or 5 (the input password is expected to already be encrypted so it will not be encrypted again). The value <pass> is the password associated with the specified name. The MD5 algorithm is encrypts the password.

Note: Newly created users are stored in the startup config file. You can also delete admin but only if you first create another level 15 user.

XSR 1800 and 3000 Series routers have an on-board Real Time Clock (RTC) chip with which to keep accurate time across the network. As an alternative to accessing a public time server, you can utilize the RTC as a time reference and propagate it by configuring XSRs as Simple Network Time Protocol (SNTP) servers or clients. XSR 1200 Series routers do not carry an RTC chip, however, and if your topology includes these devices you must synchronize them from an external source.

Enter the following command to configure the XSR as an SNTP client:

XSR(config)#sntp-client server [primary A.B.C.D.][alternate A.B.C.D.]

Enter the following command to configure the XSR as an SNTP server:
