Module: TPLINK-DHCPSNOOPING-MIB
OID (symbolic): TPLINK-DHCPSNOOPING-MIB::dhcpSnoopingPortConfigRateLimit
OID (numeric): 1.3.6.1.4.1.11863.6.27.1.3.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: 0. disable 1. 5pps 2. 10pps 3. 15pps 4. 20pps 5. 25pps 6. 30pps Select Enable/Disable the Flow Control feature for the DHCP packets. The excessive DHCP packets will be discarded.
What is dhcpSnoopingPortConfigRateLimit?
This read-write integer sets a rate limit for incoming DHCP packets on a port, choosing disable(0) or one of the fixed thresholds from 5pps up to 30pps. Per the description, packets exceeding the configured rate are discarded, giving an admin a way to throttle DHCP traffic on a port and blunt DHCP flood or denial-of-service attempts from a single host. For example, setting dhcpSnoopingPortConfigRateLimit to value10pps(10) on a lobby access port caps that port to 10 DHCP packets per second, dropping any burst above that.
