Displaying Management IP Statistics
Displaying Management IP Statistics
-
The FRAP AND T-FRAP monitor and collect statistics on TCP/IP-based management traffic (SLIP or in-band DLCI). Statistic counts are compiled on interface octet totals and protocol groups (IP, ICMP, UDP, and TCP).
-
-
To open management windows containing TCP/IP-based statistics:
-
1 Position the mouse arrow over the Unit Detail window's graphical representation of the COMM port, and click the right mouse button.
-
2 Select Management IP Statistics from the list of pull-down menu options.
-
3 Select, from the list of pull-down menu options, the type of management statistics you wish to view, and click the left mouse button. This action will cause a window, corresponding to your selection, to be displayed.
-
-
Note: The window values displayed in parentheses represents the difference (delta) between values obtained during the previous polling interval and the current interval.
-

-
Stop/Start - Clicking this button stops and starts the statistics polling action.
-
Update - Clicking this button will update (refresh) the information contained in the management statistics window.
-
Done - Clicking this button will close the management statistics window.
