Using the Hub
The MIB counters shown in Figure 5-4 are defined in Table 5-2.
Table 5-2.
Definition of MIB Counters
MIB Counter
Definition
fddiMACFrame-Ct
Number of frames received
fddiMACCopied-Ct
Number of frames copied
fddiMACTransmit-Ct
Total number of frames transmitted
fddiMACToken-Ct
Number of tokens
fddiMACError-Ct
Number of error frames

Show Neighbor Stations
To determine the hub’s upstream and downstream neighbor station addresses,
enter the
show neigh
command.
Figure 5-5 illustrates the 48-bit addresses of a
hub’s neighbors.
>sh neigh
MAC Upstream Neighbor
: 40:0A:1F:B3:CC:24
MAC Downstream Neighbor : 40:0D:4F:33:40:AE

Show Station Identification
To discover the station’s FDDI identifier and MAC address, enter the
show sid
command.
Figure 5-6 shows the results of entering this command.
>sh sid
Station ID:
00 00 02 60 8C EA EB EE
MAC/SMT Addr: 02:60:8C:EA:EB:EE (noncanonical)
LLC Addr:
40-06-31-57-D7-77 (canonical)
