What is relayVlPrimaryServerAddr?

This read-write IpAddress object sets the primary server address to which BOOTP/DHCP requests received on this VLAN are relayed. An admin configures this so client devices on a VLAN without a local DHCP server can still obtain addresses from a central server elsewhere on the network. For example, setting relayVlPrimaryServerAddr to the corporate DHCP server's IP lets clients on a remote VLAN obtain leases from that central server via relay.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.1.6.1.2
snmpwalk -v2c -c public <target> CROUTE-MIB::relayVlPrimaryServerAddr

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.1.6.1.2.1
snmpget -v2c -c public <target> CROUTE-MIB::relayVlPrimaryServerAddr.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.81.31.1.6.1.2.1 a <value>
