Module: ROUTER-OPT-MIB

OID (symbolic): ROUTER-OPT-MIB::cdx6500PCTRdefSubGwaySubnetAd

OID (numeric): 1.3.6.1.4.1.449.2.1.2.1.5.30.1.2

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-write

What is cdx6500PCTRdefSubGwaySubnetAd?

The top-level (class A, B, or C) IP network number for which this entry defines a default subnet router: if the router receives a packet for an unrecognized subnet of this network, it forwards the packet to the next hop configured in cdx6500PCTRdefSubGwayNextHopAd instead of dropping it.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.449.2.1.2.1.5.30.1.2
snmpwalk -v2c -c public <target> ROUTER-OPT-MIB::cdx6500PCTRdefSubGwaySubnetAd

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.449.2.1.2.1.5.30.1.2.1
snmpget -v2c -c public <target> ROUTER-OPT-MIB::cdx6500PCTRdefSubGwaySubnetAd.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.449.2.1.2.1.5.30.1.2.1 a <value>
