[F10-nsp] port numbler/mac address

[o k]

Ron-san,

Thank you.

I'll put the SNMP get-responses I've got from my E300 between the OIDs you 
presented. 
So, I want to know where MAC Addresses are. :-)

>- dot1qTpFdbPort : to see MAC addresses learned on non-default VLAN.

$ snmpwalk -v 2c -c public 192.168.1.1 dot1qTpFdbPort
Q-BRIDGE-MIB::dot1qTpFdbPort.20.'...-..' = INTEGER: 1
  :
(snip)
  :

* dot1qTpFdbPort  --> OID
* 20  --> VLAN ID
* '...-..' --> Is this a MAC Address? I don't know well SNMP, but I assumed 
there is a Hex or Dec value...
* 1  --> Port Number? gig0/0? If so, I want to know the mapping between 
this number and ifIndex. 

>- dot1dTpFdbPort : to see MAC addresses learned on default VLAN

$ snmpwalk -v 2c -c public 192.168.1.1 dot1dTpFdbPort
BRIDGE-MIB::dot1dTpFdbPort = No Such Instance currently exists at this OID

  #There is no port associated with the default VLAN in my E300.

>- dot1dBasePortIfIndex : to map dot1 indexes to ifIndex

$ snmpwalk -v 2c -c public 192.168.1.1 dot1dBasePortIfIndex
BRIDGE-MIB::dot1dBasePortIfIndex.0 = INTEGER: 33865785

 #It prints this one line only.

>- f10LinkAggMib : to see MAC addresses learned on LAG interfaces

$ snmpwalk -v 2c -c public 192.168.1.1 f10LinkAggMib
F10-LINK-AGGREGATION-MIB::dot3aClearFdb.0 = INTEGER: no(2)

 #There is no LAG interface configured.
