Check the clock rate and cabling on both ends. If the clock rate specified is different than what the module supports, then I believe the line will come up and go back down. (For example, the WIC-2A/S cards only support a maximum clock rate of 128K).
* Check cabling (are the DCE and DTE ends correct?) * Make sure frame-relay intf-type is set correctly on both ends (and cabling is OK) * Check clock rate (set on the interface) * Issue a "no shut" on all frame-relay interfaces on both ends of the PVC. hth, Sean -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of PING Sent: Thursday, April 11, 2002 7:43 PM To: [EMAIL PROTECTED] Subject: Re: Frame-Relay Problem [7:41250] The question is that Caslow says on page-110 that if FR switching is on, just enabling the encapsulation will bring up the PVC by using inverse arp.
