What is snRtClearArpCache?

Setting this object to clear(1) flushes the router's ARP cache table, forcing it to relearn IP-to-MAC mappings via fresh ARP requests. Admins use this after a network change, such as replacing a device's NIC, to immediately clear a stale ARP entry instead of waiting for it to age out.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1991.1.2.2.1.1
snmpwalk -v2c -c public <target> FOUNDRY-SN-RT-L3-SWITCH-GROUP-MIB::snRtClearArpCache

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1991.1.2.2.1.1.1
snmpget -v2c -c public <target> FOUNDRY-SN-RT-L3-SWITCH-GROUP-MIB::snRtClearArpCache.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1991.1.2.2.1.1.1 s <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> snRtClearArpCache.1
