Module: ALTEON-CS-PHYSICAL-MIB

OID (symbolic): ALTEON-CS-PHYSICAL-MIB::fdbSrcPort

OID (numeric): 1.3.6.1.4.1.1872.2.5.2.3.1.2.1.3

Access: read-only

Description: Either the value '0', or the port number of the port on which a frame having a source address equal to the value of the corresponding instance has been seen. A value of '0' indicates that the port number has not been learned but that the bridge does have some forwarding/filtering information about this address.

What is fdbSrcPort?

Indicates the port on which a frame with the corresponding source MAC address was last observed, or 0 if the port has not been learned. This is the primary FDB field used to determine where traffic for a given MAC address should be forwarded.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1872.2.5.2.3.1.2.1.3
snmpwalk -v2c -c public <target> ALTEON-CS-PHYSICAL-MIB::fdbSrcPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1872.2.5.2.3.1.2.1.3.1
snmpget -v2c -c public <target> ALTEON-CS-PHYSICAL-MIB::fdbSrcPort.1
