lportDCEnT3

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::lportDCEnT3

OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.73

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable specifies the time interval (secs) used to determine if lportDCEnN4 an excess number (lportDCEnN4) of Status Enquiry messages are received. This is only valid on lports using LMIREV1.

What is lportDCEnT3?

This read-write value defines the time window, in seconds, over which the DCE counts DTE Status Enquiry polls to check against the lportDCEnN4 excess-polling limit, and like N4 it is only meaningful when the port runs LMI Rev 1. An admin sets T3 in tandem with N4 as a matched pair; changing one without the other can make the excess-polling detection either far too sensitive or effectively disabled. For example, a lportDCEnT3 of 60 paired with lportDCEnN4 of 5 defines no more than 5 polls per minute as the acceptable DTE polling rate on this LMIREV1 port.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.73
snmpwalk -v2c -c public <target> CASCADE-MIB::lportDCEnT3

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.73.1
snmpget -v2c -c public <target> CASCADE-MIB::lportDCEnT3.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.73.1 i <value>
