5.5.1 Statistics
As explained in the User Guide, CES in Release 5.0 includes the following components:
• IP Address/VLAN - This makes up the IP Endpoint or IP Interface of the card (such as VLAN:402.0).
• DS1/E1 Port - The connecting point for the DS1 or E1 link.
• PSPAN - The IP-based encapsulation of the DS1 packets. This is the IP Endpoint and the unique PSPAN ID
(such as 402.0.1).
Note: In Release 5.0, only Circuit Emulation is supported, so far end statistics are not available. (In
circuit emulation, the Line and not the Path of the DS1/E1 is terminated; since the far end
statistics are embedded in the DS1/E1 frame, the Telesyn device cannot access this
information.)
5.5.1.1 IP Interface - RMON
RMON statistics can be measured for the interface using the
SHOW INTERFACE (if_name> COUNTER ON
command
5.5.1.2 DS1/E1 Interface - PMON
PMON statistics/thresholds for DS1/EI are similar to those for ADSL and SHDSL cards. Table 5-2 lists the sta-
tistics and any guidelines for setting thresholds and viewing historical trends.
