nwAtFwdIfCtrFilteredBytes

Module: CTRON-AppleTalk-ROUTER-MIB

OID (symbolic): CTRON-AppleTalk-ROUTER-MIB::nwAtFwdIfCtrFilteredBytes

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.4.2.2.2.2.1.1.16

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: Indicates the total number of bytes in the AppleTalk packets that have been administratively filtered, during nwAtFwdIfCtrOperationalTime, on the router port for which the entry exists.

What is nwAtFwdIfCtrFilteredBytes?

This read-only Counter totals the bytes in AppleTalk packets administratively filtered on a specific router port during the current nwAtFwdIfCtrOperationalTime interval. An administrator uses it to gauge, in bandwidth terms, how much traffic a per-port ACL is blocking on that link. A large nwAtFwdIfCtrFilteredBytes value on one port might indicate that port's ACL is overly aggressive relative to its peers.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.4.2.2.2.2.1.1.16
snmpwalk -v2c -c public <target> CTRON-AppleTalk-ROUTER-MIB::nwAtFwdIfCtrFilteredBytes

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.4.2.2.2.2.1.1.16.1
snmpget -v2c -c public <target> CTRON-AppleTalk-ROUTER-MIB::nwAtFwdIfCtrFilteredBytes.1
