ctAgentDaiVlanDhcpPermits
Module: CT-FASTPATH-DYNAMIC-ARP-INSPECTION-MIB
OID (symbolic): CT-FASTPATH-DYNAMIC-ARP-INSPECTION-MIB::ctAgentDaiVlanDhcpPermits
OID (numeric): 1.3.6.1.4.1.52.4.2.36.1.1.6.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of ARP packets that were forwarded by DAI as there is a matching DHCP Snooping binding entry found.
What is ctAgentDaiVlanDhcpPermits?
This read-only Counter32 tracks ARP packets forwarded by DAI because a matching entry was found in the DHCP Snooping binding table for that VLAN. An administrator watches this as confirmation that DHCP-leased devices are being correctly validated and allowed to communicate. For example, a healthy VLAN using DHCP Snooping and DAI together should show ctAgentDaiVlanDhcpPermits growing steadily as normal client ARP traffic is validated and passed.
