Edit: It could also be mismatched encapsulation commands. 1. This phrase indicates that the interface will be down after three tries, but that doesn't mean it will increment the "interface resets" counter.

The NID may be located outside where the cables come into the house, or may be located inside of the house in a utility area. The value in this field identifies the datagram encapsulated in the Information field of the packet. IP (Internet Protocol) addresses are used to specify the location of each computer on the network. Generally if only the protocol portion shows as down it is related to configurations that don't match on the devices that are connected. Over the next hour, he came out 2 more times before I finally just let him join me in the living room so he doesn’t wake up his brother and sister by going back-n-forth. Solution to troubleshoot such problem is given below: It specifies that the HDLC frame be byte-aligned with the SONET frame, and also specifies a self-synchronizing scrambler, a cyclic redundancy check (CRC), and use of the HDLC flag pattern as the interframe fill to account for the variable nature of arriving HDLC frames. Staring off into space at times as well. LCP uses Terminate packets to close the link. Identifier—On transmission, the Identifier field must be changed whenever the content of the Data field changes and whenever a valid reply has been received for a previous request. Nice to have these discussions. I think it helps explain a little. RFC 2615 specifies the use of PPP encapsulation over SONET or SDH links. IEEE 802.11 is a set of LAN protocol that sets a standard for the communication between the server and the device that is firestick and the wifi. The trailer provides error checking. When an external event, such as carrier detection or network administrator configuration, indicates that the physical layer is ready to be used, PPP proceeds to the link establishment phase. Here's what I get from a sh int f0/0. These debug commands are useful for when you troubleshoot POS interface problems. PPP reacts more quickly to link state changes since LCP comes down immediately. My wife woke me up a couple of hours later telling me something was wrong with it. The other side is encapsulation PPP so that’s not going to work.

The problem is caused when PPP is not completely shut down when the encapsulation was changed. The reasons a catalyst switch can go into Errdisable mode and shutdown a port are many and include: When a port is in error-disabled state, it is effectively shut down and no traffic is sent or received on that port. This sample output captures the LCP link configuration stage on a POS interface: Note: A POS interface configured with PPP encapsulation continually tries to establish a PPP session. An interface going down completely does not increase the counter, as it has been in practice, even rapidly, shutdown and came up right back again.
