RE: Cisco uBR924 and Internet problems... [7:61754]
Hi Leonardo, Basically, you're answering your own question: the provider lets you download a file that disables your service. Normally, this file specifies the Class Of Service you get from your provider, like upstream and downstream bandwidth. Now for some reason, the provider doesn't want to give you any service and therefore let you download a file which denies access. There is one thing that I don't understand, though. If you didn't buy this modem from your provider (or did you?) then the modem's MAC address is not registered with them. Therefore, why would they allow the DHCP server to give your modem an IP address? That doesn't make sense. On the other hand, if you did buy the modem from the ISP, then like I said, they just doesn't want to give you access for some reason (not paying your subscription fee springs to mind ;)) Bottom line: you have to contact them.

[7:61754] Hello everyone!! I have a question here, I need your help! Recently I bought a Cisco uBR924 and I've been trying to connect it at home, so I can expand my home lab capabilities. My service provider is Time Warner (Road Runner) and I simply can't connect it to the Internet. This router has one cable-modem interface, four ethernet ports (represented as 1 ethernet interface) and two FXS voice-ports. According to the Cisco's documentation, the service establishment process of a cable-modem-router like this one is as follows: - Scan for a downstream channel and establish synchronization with the CMTS. - Obtain upsteam channel parameters. - Start ranging for power adjustments. - Establish IP connectivity - Establish the time of day - Establish security - Transfer operational parameters - Perform registration - Comply with baseline privacy - Enter the operational maintenance state When I issue show int cable-modem 0, I notice a lot of interface resets displayed by the output. Further investigation required me to run some debug commands and - I love this one - show controllers cable-modem 0 mac log, which probably identified the problem. I could see almost all CMAC_LOG_STATE_CHANGE events, but during the registration process (registration_state), the modem received a RESET_AUTHENTICATION_FAILURE. I pasted part of the output so my question may be answered by someone: The steps from scanning downstream to establish security seem to be fine: 1041.159 CMAC_LOG_STATE_CHANGE wait_for_link_up_state 1041.159 CMAC_LOG_STATE_CHANGE ds_channel_scanning_stat 1043.540 CMAC_LOG_STATE_CHANGE wait_ucd_state 1046.319 CMAC_LOG_STATE_CHANGE wait_map_state 1046.371 CMAC_LOG_STATE_CHANGE ranging_1_state 1047.337 CMAC_LOG_STATE_CHANGE ranging_2_state 1048.112 CMAC_LOG_STATE_CHANGE dhcp_state 1048.404 CMAC_LOG_DHCP_ASSIGNED_IP_ADDRESS 10.47.170.200 1048.404 CMAC_LOG_DHCP_TFTP_SERVER_ADDRESS 24.29.99.72 1048.404 CMAC_LOG_DHCP_TOD_SERVER_ADDRESS24.29.99.72 1048.404 CMAC_LOG_DHCP_SET_GATEWAY_ADDRESS 1048.404 CMAC_LOG_DHCP_TZ_OFFSET 0 1048.404 CMAC_LOG_DHCP_CONFIG_FILE_NAME disabled.bin 1048.404 CMAC_LOG_DHCP_ERROR_ACQUIRING_SEC_SVR_ADDR 1048.404 CMAC_LOG_DHCP_LOG_SERVER_ADDRESS24.29.99.57 1048.404 CMAC_LOG_DHCP_COMPLETE 1059.956 CMAC_LOG_STATE_CHANGE establish_tod_state 1059.956 CMAC_LOG_TOD_REQUEST_SENT 24.29.99.72 1059.964 CMAC_LOG_TOD_REPLY_RECEIVED 3252376461 1059.968 CMAC_LOG_TOD_COMPLETE 1059.968 CMAC_LOG_STATE_CHANGE security_association_state 1059.968 CMAC_LOG_SECURITY_BYPASSED But when the modem downloaded de DOCSIS configuration (the config file), I noticed something weird: 1059.968 CMAC_LOG_STATE_CHANGE configuration_file_state 1059.968 CMAC_LOG_LOADING_CONFIG_FILEdisabled.bin 1063.988 CMAC_LOG_CONFIG_FILE_PROCESS_COMPLETE Did you noticed the filename received by the Cisco uBR924? Its name is DISABLED.BIN. It doesn't sound good.. After that, the next step is registration. Now I noticed that the CTMS has, for an unknown reason, rejected the registration process.

RE: recover lost password WITHOUT losing config on 2500 router [7:57384]
If you copied you running config to startup config then there shouldn't be a problem. Set the confreg to 0x2142, which causes the router to startup without getting its config. When it's back up, go into enable mode. There isn't a password obviously. Then do a copy start run, and change the password.

All 4 sites are on different subnets. At Site A a Catalyst 3550G with 12 available fiber GBIC connections is what the 3 incoming sites B,C, and D connect to on GBIC interfaces 1,2, and 3, respectively.. The 3550G also has two Ethernet ports on it, one which has a crossover to a Catalyst 3548 switch, which feeds the local LAN users at Site A itself. Interface GBIC 4 on the 3550G has a fiber link connecting to Site E, which is then routed over ATM. So basically the 3550 at Site A routes traffic between itself and the B,C, and D sites and over to Site E. Site E is actually our core router site (Cisco 3540) but Site A was chosen to hosts the other 3 sites (B,C,and D) due to logistics. Now what I need to do back at Site A is segment the local LAN on the 3548 switch into two vlans. Both vlans need to pass traffic across the network. Remember one port on the 3548 has a crossover to the 3550G switch. The 3550G is not set up with vlans. If I break the ports on the 3548 to the vlan's I want, I assume I set the crossover port to be a trunk? And if so, do I need to setup the other end of the crossover on the 3550 with any vlan's or trunking??? No other subnets will be broken into vlan's so I want to make sure any change I may have to make on the 3550 to support the local vlans on the 3548 do not hinder traffic flow to and from the other sites interfaces on the 3550. Am I over complicating this setup? I know my description probably is confusing. I guess in simple terms I just need to make sure how I set up vlans on the local Site A without affecting the other sites that Site A supports?

RE: serial up, line ptotocol up..for a while [7:56515]
10 seconds? That almost sound like the keepalive time setting. After the no shut, the router tried to bring the interface up, sending a keepalive to the other side, but it didn't receive anything back so it brought the interface down again. You may want to check the way you are receiving you're clock and if the encapsulation is the same on both sides of the serial link.

I have a probem with some cable modems. The fact is that in the network there are around 150 cable modems and the uBR can't see more than 90. I tried a: 'clear cable modem all reset' and the same no of modems is seen(90). This command won't reach the modems that you can't see of course, so those modems won't be reset. The problem was that we had a power outage and the uBR was reset.. If the cable modems are hardware reset, the uBR sees them. I assume there has to be a way to solve this problem without going to each and every customer and reset the cable modem.. When a modem looses the frequency it was acquired on, it starts scanning for another one. At first, it takes steps of (I believe) 3 MHz. So it doesn't take a very long time to go through the whole spectrum. But when it still can't find a frequency, it starts scanning in steps of 125 kHz. And then it can take an awfull lot of time for the modem to acquire again. When you reboot the modem, it will start looking for the frequency it was last acquired on, before it starts scanning. So that's why a modem comes online immediately after a power cycle. Maybe you're just not waiting long enough for the modem to re-acquire again? It would be interesting to see what the modem is doing, so maybe you can get a friendly customer to look at that via the web browser? (If that's possible, as I don't know the make of the modem) At least then you know if the modem is scanning or just locked up. Hope that helps.

RE: Frame Relay: connectionless or connection-oriented? [7:54707]
Some documentation may say that it's connection oriented because you have to set up a PVC (or an SVC) so you pre-establish a connection. But in fact it's connectionless, since it doesn't have, like you say, a retransmission system or error checking mechanism like TCP. And the terms connection oriented and connectionless, refer to the protocol, not to the circuit. Peter -Original Message- From: B.J.

RE: Frame Relay: connectionless or connection-orie [7:54707]
Thinking of the subject again, I would have to come back to what I've said before. TCP is connection oriented because there's the three-way handshake session establishment. It's reliable because of the retransmission and error checking mechanismns. UDP is connectionless, because there's no session establishment and it's unreliable because of a lack of retransmission and error checking mechanismns. Frame relay is connection oriented because of the establishment of a circuit, but unreliable because there are no retransmission and error checking mechanismns. X25 is connection oriented and reliable. Peter -Original Message- From: B.J.

In other words, does it perform a check to make sure every single IP packet (or Frame Relay frame) makes it from the ingress point of the Frame cloud to the egress point? I don't believe it does, and therefore I consider it connectionless. Now, from a *test* perspective (g...), I suppose the correct answer is connection-oriented due to the reasons that Peter specified.
