Interpreting Data VC statistics
The Statistics > Data VC page displays information about Virtual Channel (VC) used in data
communications. This page is applicable for all modules (AP/SM/BHM/BHS).
The Data VC tab displays the fields as explained in Table 214.
Table 214 Data VC page attributes
Attribute
Meaning
Subscriber
This field displays the LUID (logical unit ID), MAC address and Site Name
of the SM/BHS. As each SM or BHS registers to the AP/BHM, the system
assigns an LUID of 2 or a higher unique number to the SM/BHS. If a
SM/BHS loses registration with the AP/BHM and then regains
registration, the SM/BHS retains the same LUID.
VC
This field displays the virtual channel number. Low priority channels
start at VC18 and count up. High priority channels start at VC255 and
count down. If one VC is displayed, the high-priority channel is disabled.
If two are displayed, the high-priority channel is enabled.
CoS
This field displays the Class of Service for the virtual channel. The low
priority channel is a CoS of 00 and the high priority channel is a CoS of
01. CoS of 02 through 07 are not currently used.

This field displays how many octets were received on the interface,
including those that deliver framing information.

broadcast or subnetwork-multicast) packets were delivered to a higher-
