hi,
Refer to the link: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/wan_ c/wcdfrely.htm#xtocid2218540 Frame Relay end-to-end keepalives enable monitoring of PVC status for network monitoring or backup applications and are configurable on a per-PVC basis with configurable timers But I can't understand how to use this feature for backup. Could any one tell me? -- ShanJun Zou [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=23831&t=23831 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
