virtualUNIT398

Module: ACMIB

OID (symbolic): ACMIB::virtualUNIT398

OID (numeric): 1.3.6.1.4.1.1751.2.18.5.19.1.23

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: Timer T398 value - seconds

What is virtualUNIT398?

This OID configures the timeout duration (in seconds) for ATM signaling timer T398, which is specific to certain UNI procedures and connection management sequences. Engineers modify this value when they encounter timing-related connection failures or need to optimize performance for particular circuit types. A value of 8 seconds would mean the system allows 8 seconds for a specific handshake step before retrying.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.19.1.23
snmpwalk -v2c -c public <target> ACMIB::virtualUNIT398

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.19.1.23.1
snmpget -v2c -c public <target> ACMIB::virtualUNIT398.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.19.1.23.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> virtualUNIT398.1
