On both the DECrepeater 900TM and 900TP ... port level information
provides last known MAC address ... thru HUBwatch ... Customer is
writing "home grown" application that runs in batch mode at various
odd hours of the day ... Is this last known address available through
either MIB or MIB extensions ...
CSecond question based on above ... how long will repeater keep last
MAC address around ... i.e. if a 900TP has 24 People attached all day
... but at the end of the day 15 of these 24 people turn off their PCs
when they go home ... wil the repeater/HUBwatch keep the 15 addresses
of the PCs that were turned (powered off) off. ... if so for how
long???

| 3627.1 | Use rptrAddrTrackNewLastSrcAddress in RFC 1516 | NETCAD::PAGLIARO | Rich Pagliaro, Networks BU, HPN | Mon Jun 17 1996 10:20 | 27 |
RFC 1516 defines the following object to report the last source address
seen on a port.
rptrAddrTrackNewLastSrcAddress OBJECT-TYPE
SYNTAX OCTET STRING (SIZE(0 | 6))
ACCESS read-only
STATUS mandatory
DESCRIPTION
"This object is the SourceAddress of the last
readable frame (i.e., counted by
rptrMonitorPortReadableFrames) received by this
port. If no frames have been received by this
port since the agent began monitoring the port
activity, the agent shall return a string of
length zero."
REFERENCE
"Reference IEEE 802.3 Rptr Mgt, 19.2.6.2,
aLastSourceAddress."
::= { rptrAddrTrackEntry 5 }
The DECrepeaters will retain a given address until it is either (a)
overwritten by the reception of a frame with a different source
address, or (b) the repeater is reset. That is, these entries are not
designed to age out like the entries in the erptrAddrDBPortAddrTable
table defined in DEC extended repeater MIB.
