h248MaxNumberOfContexts
Module: ACMIB
OID (symbolic): ACMIB::h248MaxNumberOfContexts
OID (numeric): 1.3.6.1.4.1.1751.2.18.31.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The value of the property gives the maximum number of contexts that can exist at anytime. The NULL context is not included in this number.
What is h248MaxNumberOfContexts?
This OID sets the maximum number of media gateway contexts (logical call sessions) that can exist simultaneously, excluding the special NULL context. Engineers configure this to control resource usage and prevent overload—higher values allow more concurrent calls but consume more memory. For example, setting it to 1000 allows up to 1000 simultaneous call contexts, while 100 limits it for gateways with less memory.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.31.1 snmpwalk -v2c -c public <target> ACMIB::h248MaxNumberOfContexts
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.31.1.1 snmpget -v2c -c public <target> ACMIB::h248MaxNumberOfContexts.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.31.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> h248MaxNumberOfContexts.1
