h3cDhcpSnoop2IfMaxLearnNum
Module: H3C-DHCP-SNOOP2-MIB
OID (symbolic): H3C-DHCP-SNOOP2-MIB::h3cDhcpSnoop2IfMaxLearnNum
OID (numeric): 1.3.6.1.4.1.2011.10.2.124.2.2.1.6
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The maximum number of binding entries that could be learned on the port. If the value is 0, it means that there is no threshold on the port.
What is h3cDhcpSnoop2IfMaxLearnNum?
Limits how many binding entries can be learned on this port, with 0 (the default) meaning no cap. Setting this to, say, 1 on a single-host access port prevents a compromised or misconfigured device from exhausting the binding table with spoofed leases.
