Link Monitor Threshold Snr - Cisco Catalyst 2950 Command Reference Manual

link monitor threshold snr

link monitor threshold snr
Use the link monitor threshold snr interface configuration command to establish threshold values for
signal-to-noise ratio (SNR) errors. Use the no form of this command to return to the default setting.
This command is available only on Catalyst 2950 Long-Reach Ethernet (LRE) switches.
Syntax Description downstream value
upstream value
Defaults The default is 2 dB.
Command Modes Interface configuration
Command History Release
12.1(11)YJ
Usage Guidelines The default theoretical SNR value added to the threshold value is compared to the value in the LRE
chipset.
Examples This example shows how to configure the SNR threshold as 6 dB downstream and 4 dB upstream:
Switch# configure terminal
Switch(config)# interface longreachethernet0/1
Switch(config-if)# link monitor threshold snr downstream 6
Switch(config-if)# link monitor threshold snr upstream 4
