Module: DOCS-L2VPN-MIB
OID (symbolic): DOCS-L2VPN-MIB::docsL2vpnCmDhcpSnooping
OID (numeric): 1.3.6.1.4.1.4491.2.1.8.1.3.1.4
Node type: OBJECT-TYPE
Type: DocsL2vpnIfList
Access: read-only
Description: This object reports the value of the Enable DHCP Snooping subtype of a top-level L2VPN Encoding.
It has the syntax of a CM Interface List bitmask and represents a set of CM MAC bridge interfaces corresponding to eSAFE hosts for which the CMTS is enabled to snoop DHCP traffic in order to learn the eSAFE host MAC address on that interface.
Only bits corresponding to eSAFE host MAC addresses may be validly set in this object, including cpe(1) for ePS and the eSAFE interfaces in bits positions 16 through 31.
What is docsL2vpnCmDhcpSnooping?
The Cable Modem Interface Mask identifying which eSAFE host interfaces the CMTS is enabled to snoop DHCP traffic on, used to learn each eSAFE host's MAC address; only bits for eSAFE-type interfaces (including cpe(1) for ePS and bit positions 16-31) may validly be set.
