Viewing T1/E1 Local Statistics
There are a number of commands available for viewing local
T1
and
E1
statistics. These
commands provide statistics for the past 24 hours, the current 15-minute interval, or the past
96 15-minute intervals. The following sections describe these commands.
Viewing Total Local Statistics
You can view statistics occurring during the past 24 hours on a single port by entering the
following command
telts <slot>/<port>
where
<slot>
is the slot number where the board is located, and
<port>
is the port number on
the board for which you want to view statistics. For example, to view 24-hour statistics for
Port 2 on the board in slot 5, enter
telts 5/2
A screen similar to the following displays:
