Broadband Clarity works based on the ADSL-LINE-MIB and the VDSL-LINE-MIB.
The ADSL-LINE OIDs we look at are the same as for bandwidth discovery:
adslAtucChanCurrTxRate
Inbound ADSL bandwidth (downstream)
adslAturChanCurrTxRate
Outbound ADSL bandwidth (upsteam)
The specific OIDs in the VDSL-LINE used is more complex as it's a table rather than a straight OID look up. Comtrend devices use the VDSL-LINE-MIB; other vendors may also use this MIB.
Highlight provides a workaround for Cisco FTTC / VDSL2 services. Instead of looking at the parent of the Ethernet0 for the sync speed, Highlight retrieves the bandwith from a non-existent ADSL-ATM0 interface.
Highlight can support multiple DSL interfaces on a router so long as the stack table is correct.
