Module: GBNL2DhcpSnooping-MIB
OID (symbolic): GBNL2DhcpSnooping-MIB::vlanMaxNum
OID (numeric): 1.3.6.1.4.1.13464.1.2.4.5.3.1.2
Node type: OBJECT-TYPE

Description: Max clients in this vlan.Range is from 0 to 2048.Default is 2048.
What is vlanMaxNum?
This value caps how many DHCP clients are allowed to be learned within a specific VLAN under DHCP snooping, mirroring the per-port limit but applied at the VLAN scope instead, defaulting to 2048. Administrators tune this to protect against a flood of DHCP requests across an entire VLAN, complementing the finer-grained per-port limit. For example, an admin managing a VLAN with a known, limited number of expected devices might lower this from the default 2048 down to a smaller number appropriate to that VLAN's actual device count.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.13464.1.2.4.5.3.1.2 snmpwalk -v2c -c public <target> GBNL2DhcpSnooping-MIB::vlanMaxNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.13464.1.2.4.5.3.1.2.1 snmpget -v2c -c public <target> GBNL2DhcpSnooping-MIB::vlanMaxNum.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.13464.1.2.4.5.3.1.2.1 i <value>
