Gathering and Viewing Call Statistics
3.3 Using SNMP
Modem connect speeds can be graphed using SNMP MIBs. The graph shown in Figure 6-2 was created
with Cisco Access Manager (CAM). The graph describes the modem connect-speed performance
activity of one NAS for one month. The following connect speeds are transmitted by the NAS and
received by the client modem. Most of the calls performed between 28000 and 31200 bps. This NAS is
one member of an access stack.
