xdhcpRelayMaxHops
Module: XEDIA-DHCP-MIB
OID (symbolic): XEDIA-DHCP-MIB::xdhcpRelayMaxHops
OID (numeric): 1.3.6.1.4.1.838.3.28.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This value identifies the maximum number of hops allowed for requests passing through this relay agent. Packets received with a hop count greater than this value will be discarded.
What is xdhcpRelayMaxHops?
This value sets the maximum number of relay agent hops a DHCP request may have accumulated before this relay agent discards it. Admins tune it to prevent DHCP request loops or excessive relay chains, dropping packets that have already passed through too many relay agents. The default 4 discards any DHCP packet whose hop count already exceeds 4 when it reaches this relay agent; lowering it to 2 would more aggressively limit acceptable relay chain length.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.838.3.28.1.1.2 snmpwalk -v2c -c public <target> XEDIA-DHCP-MIB::xdhcpRelayMaxHops
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.838.3.28.1.1.2.1 snmpget -v2c -c public <target> XEDIA-DHCP-MIB::xdhcpRelayMaxHops.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.838.3.28.1.1.2.1 i <value>
