saCmArpRateLimit
Module: SA-CM-MIB
OID (symbolic): SA-CM-MIB::saCmArpRateLimit
OID (numeric): 1.3.6.1.4.1.1429.77.1.3.19
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Setting ARP rate-limit defines the number of ARP packets that can be processed per second. Limitation of this number prevents denial-of-service attacks. A value of 20 pps is a good reference. Setting the value to 0 allows unlimited incoming ARP messages
What is saCmArpRateLimit?
Caps how many ARP packets per second the modem will process (0-100, default 0 meaning unlimited); an operator sets a value like 20 pps as a sensible ceiling to blunt ARP-flood denial-of-service attempts against the modem.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1429.77.1.3.19 snmpwalk -v2c -c public <target> SA-CM-MIB::saCmArpRateLimit
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1429.77.1.3.19.1 snmpget -v2c -c public <target> SA-CM-MIB::saCmArpRateLimit.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1429.77.1.3.19.1 i <value>
