The reboot command resets the unit, which allows physical attributes to be set, and the
command has no arguments. It is only visible when the unit is logged in. After reboot, the OA&M
interface returns to the logged-out mode.
The reboot command will always prompt for a password for validation purposes even if the
administrator is logged at the appropriate level or higher.
5.2.12 REMOVE
Syntax: remove
The remove or rm command takes the unit out of service. This command must be performed
before any module level configuration changes can occur. It is only visible when the unit is logged
in. The command has no arguments.
The remove command will always prompt for a password for validation purposes even if the
administrator is logged at the appropriate level or higher.
5.2.13 RESTORE
Syntax: restore
The restore or rs command returns the Universal Trunk to service, and it has no arguments. If
any physical attribute was changed on the unit, including the MAC address, the unit will be
automatically rebooted by this command.
5.2.14 PING
Syntax: ping <IP Address> [ Interval Seconds ]
The ping command is only visible when the unit is logged in. The command has a single required
argument, the IP address that is to be pinged.
The ping command formats an ICMP echo request packet that is then sent to the IP Address
specified. The device with that address will issue an ICMP echo reply to the request. This is
required of all IP implementations by RFC 791. If a reply is received, an informational alarm is
issued on the UMI console. If no reply is received, there is a timeout message that will appear for
that ICMP echo request.
The ping command issues a single ICMP echo request packet and awaits a response. The
response is printed, and another ICMP echo request is issued. The operation continues until the
user presses any character. The [ Interval Seconds ] argument specifies the amount of time to
wait in seconds between the individual ICMP echo requests.
It should be noted that some host Internet Protocol implementations issue duplicate responses to
a single ICMP request. The ping command will suppress duplicate replies.
