hcxStuSrcIpAddrIPMask

Module: COM21-HCXSTU-MIB

OID (symbolic): COM21-HCXSTU-MIB::hcxStuSrcIpAddrIPMask

OID (numeric): 1.3.6.1.4.1.1141.2.52.1.1.3

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-write

Description: IP mask for ComPort. Default is ff.ff.ff.ff.

What is hcxStuSrcIpAddrIPMask?

This read-write IpAddress specifies the subnet mask paired with the allowable source IP address entry, defaulting to ff.ff.ff.ff (a full host mask), per the description. An admin adjusts this if a range of addresses rather than a single host should be permitted for this ComPort's source filtering entry. For example, an admin leaves hcxStuSrcIpAddrIPMask at the default full-host mask when a subscriber has exactly one static IP that should be allowed, rather than a whole subnet.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1141.2.52.1.1.3
snmpwalk -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuSrcIpAddrIPMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1141.2.52.1.1.3.1
snmpget -v2c -c public <target> COM21-HCXSTU-MIB::hcxStuSrcIpAddrIPMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1141.2.52.1.1.3.1 a <value>

SNMPv3 example:

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