Module: TPLINK-DHCPSNOOPING-MIB
OID (symbolic): TPLINK-DHCPSNOOPING-MIB::dhcpSnoopingPortConfigDeclineRateLimit
OID (numeric): 1.3.6.1.4.1.11863.6.27.1.3.1.1.5
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 decline packets. The excessive DHCP decline packets will be discarded.
What is dhcpSnoopingPortConfigDeclineRateLimit?
This read-write integer sets a rate limit specifically for DHCP decline packets on a port, choosing disable(0) or one of the fixed thresholds from 5pps up to 30pps. Per the description, decline packets above the configured rate are discarded, letting an admin curb a host that repeatedly sends DHCPDECLINE messages, a pattern sometimes used to exhaust the DHCP server's address pool. For instance, an admin sets dhcpSnoopingPortConfigDeclineRateLimit to value5pps(5) on a suspect port to limit it to 5 decline packets per second.
