#that the index should correlate to dot1dbaseport, however

#limits the index to 4096 while dot1dbaseport can go much higher

#confirmed on various switches that this index cannot be numerically correlated
|
|
#to if-mib in a reliable fashion immediately for all switches
|
|
#LldpPortIdSubtype dictates the format
|
|
#in order of preference on subtype:
|
|
#if 5, then portid==ifName (my favorite, least work, no further lookups)
|
|
#if 3, then may be able to link into IF-MIB via ifPhysAddress matching more reliably
|
|
#if 7, then it may be anything at all, portDesc may be best option when encounterd, though occasionally looks like a 5. In the cases where it looks like a 5,
|
|
#portdesc seems usable too.
|
|
#detailed switch by switch results below
|
|
#on Force10, the following happens:
|
|
# -index violates mib by going over max value
|
|
# -subtype is 5, meaning portid should be == ifName, usable
|
|
# -lldpPortDesc is blank, cannot be used
|
|
#on juniper:
|
|
# -index violates mib by not matching dot1dbaseport
|
|
# -lldpPortId is 'helpfully', the index in ascii form (gee thanks), useless example of type 7
|
|
# -lldpPortDesc looks like "ge-1/0/43.0",only hope.

MacMap attempts to do it's best to determine whether or not a particular SNMP description of
|
|
a port matches the user specified value in the configuration. Generally, if the configuration
|
|
consists of non-stacked switches without line cards, the user should only need to specify the
|
|
port number without any characters or / characters. If the configuration contains line cards
|
|
or stacked switches, use of that particular switch's appropriate / syntax in generally called
|
|
for. The exception being stacked SMC 8848 switches, in which all ports are still single
|
|
numbers, and the ports on the second switch begin at 57.
|
|
|
|
If difficulty is encountered, or a switch is attempted with a format that doesn't match any
|
|
existing rule, it is recommended to use snmpwalk on the switch with the .1.3.6.1.2.1.31.1.1.1.1
|
|
OID, and have the switch table port value match exactly the format suggested by that OID.
