jnxIpv4AdEntNetMask

Module: JUNIPER-IPv4-MIB

OID (symbolic): JUNIPER-IPv4-MIB::jnxIpv4AdEntNetMask

OID (numeric): 1.3.6.1.4.1.2636.3.12.1.1.1.3

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-only

Description: The subnet mask associated with the IP address of this entry. The value of the mask is an IP address with all the network bits set to 1 and all the hosts bits set to 0.

What is jnxIpv4AdEntNetMask?

This object reports the subnet mask associated with a specific IPv4 address configured on the device, expressed as an IP-address-formatted value with network bits set to 1 and host bits set to 0. An admin reads this to determine the size of the subnet that address belongs to, needed for routing and troubleshooting. For example, a jnxIpv4AdEntNetMask of 255.255.255.0 tells the admin the associated address belongs to a /24 subnet.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.12.1.1.1.3
snmpwalk -v2c -c public <target> JUNIPER-IPv4-MIB::jnxIpv4AdEntNetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.12.1.1.1.3.1
snmpget -v2c -c public <target> JUNIPER-IPv4-MIB::jnxIpv4AdEntNetMask.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> jnxIpv4AdEntNetMask.1
