hpicfDhcpSnoopVlanEnable
Module: HP-ICF-DHCP-SNOOP-MIB
OID (symbolic): HP-ICF-DHCP-SNOOP-MIB::hpicfDhcpSnoopVlanEnable
OID (numeric): 1.3.6.1.4.1.11.2.14.11.5.1.34.1.1.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: The administrative status for DHCP Snooping on each VLAN. There will be one bit in this string for each possible VLAN ID. Each octet within this value specifies a set of eight VLANs, with the first octet specifying VLAN IDs 1 through 8, the second octet specifying VLAN IDs 9 through 16, etc. Within each octet, the most significant bit represents the lowest numbered VLAN ID, and the least significant bit represents the highest numbered VLAN ID. Thus, each possible VLAN ID of the bridge is represented by a single bit within the value of this object. If a bit at position 'n' has a value of '1', then DHCP Snooping is enabled on VLAN 'n'. If this bit has a value of '0',DHCP Snooping is not enabled on the VLAN 'n',
What is hpicfDhcpSnoopVlanEnable?
This octet-string bitmap controls which VLANs have DHCP Snooping active, with each bit representing one VLAN ID -- the first octet covers VLANs 1-8, the second 9-16, and so on -- where a '1' bit means snooping is enabled on that VLAN. An admin manipulates specific bits rather than a single global flag to enable snooping only on VLANs that carry client DHCP traffic, such as VLAN 10, while leaving trunk or management VLANs unaffected.
