Displaying Interface Statistics (RMON) (CLI)
IP-20 stores and displays statistics in accordance with RMON and RMON2
standards.
To display RMON statistics for a physical interface, go to interface view for the
interface and enter the following command:
eth type eth [x/x]>rmon statistics show clear-on-read <clear-
on-read> layer-1 <layer-1>
Table 145: Interface Statistics (RMON) CLI Parameters
Parameter
Input Type
Permitted
Values
Description
clear-on-read Boolean
yes
no
If you enter yes, the statistics are cleared once you
display them.
layer-1
Boolean
yes
no
yes
–
Statistics are represented as Layer 1 statistics,
including preamble and IFG.
no
–
Statistics are represented as Layer 2 statistics.
Example
The following commands enter interface view for GbE 1, and clear the
statistics after displaying them.
root> ethernet interfaces eth slot 1 port 1
eth type eth [1/1]>rmon statistics show clear-on-read yes
layer-1 yes
The following commands enter interface view for radio carrier 1 in an IP-20C
or IP-20S unit, and display statistics for the interface, without clearing the
statistics.
root> ethernet interfaces radio slot 2 port 1
eth type radio[2/1]>rmon statistics show clear-on-read no
layer-1 no

Configuring Automatic State Propagation (CLI)
Automatic state propagation enables propagation of radio failures back to the
Ethernet port. You can also configure Automatic State Propagation to close the
Ethernet port based on a radio failure at the remote carrier.
You must first configure automatic state propagation for a pair consisting of
an Ethernet interface, on the one hand, and a radio interface, Multi-Carrier
ABC group, or HSB protection group, on the other. You must then use a
separate command to enable automatic state propagation on the selected pair
and determine whether a failure on the remote side of the link is propagated
to the local interface.
It is recommended to configure both ends of the link to the same Automatic
State Propagation configuration.
