Re: (usr-tc) Total Control loosing dialup connections...

Have you looked at the retrains in the session monitor? If they're going up like wildfire you have your answer. Also compare ping times on your customers from time to time and see what's going on on average. You might have a faulty PRI or T1 or a CLEC time/framing issue (bi-polar violations). Those bi/po's are hard to pin down sometimes. Each vendor in the loop points at the other one, and if it were Verizon, they'd say you are crazy and the circuit is fine :) Been there. Good luck.

(usr-tc) Total Control loosing dialup connections...
by Clint Alexander 10 Sep '01

10 Sep '01

I have a 3com Total Control hub V4.1.59, with 7 DSP modem cards. I'm getting a ton of complaints from dialup users that all "receiving traffic" stops, while they are surfing, or checking mail, or whatever. I've monitored one of these users via (monitor ppp), and notice that I am receiving the PPP packets from the user, but nothing is being sent back. I try to ping the IP of the modem, and I get a timeout. There is a route in the routing table, for their IP, and it did point to their modem port. I checked the status of the port (show int slot:#/mod:#) , and it shows nothing out of the ordinary. I realize that it could be the phone lines, but I have to be sure. Has anyone came across this problem before, or know of a better way I can confirm -where- the problem is ? - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.

(usr-tc) OSPF doesn't announce RADIUS learned addresses?
by Antonio Querubin 05 Sep '01

05 Sep '01

I'm trying to convert from RIP to OSPF on a pair of HIPERARCs and so far OSPF is able to announce the addresses in the multi-aggregate address pools to the rest of the net. It's picking up routes from the other devices (a mix of Ciscos, Redbacks, Junipers, and Ascend MAX) as well as the default route from our border routers. However, when a PPP dialer receives their IP address via RADIUS instead of from the configured address pool, OSPF doesn't announce the address. The address is seen if one does a 'list ip network' and it's pingable. But none of the other devices on the LAN receive any announcement from the HIPERARC. I do have an OSPF sendpolicy that covers every possible address we might announce. If I revert back to RIP, the address learned from RADIUS is announced via RIP. Anybody have an idea on what I might be missing here? anunu2> show ospf global GLOBAL OSPF SETTINGS Router ID: 64.65.64.36 Administrative Status: ENABLED OSPF Version Number: 2 Area Border Router Status: DISABLED Autonomous System Border Router Status: DISABLED Type-of-service (TOS) Support: OFF External LSDB Limit: -1 Multicast Extensions Support: OFF Exit Overflow Interval: 0 Router's Support for OSPF Demand Routing: OFF OSPF Traps: ENABLED anunu2> list ospf host OSPF HOST TABLE HostIpAddr/Mask Metric AreaId 64.65.75.176/28 1 0.0.0.1 64.65.75.192/26 1 0.0.0.1 64.65.76.0/26 1 0.0.0.1 64.65.76.64/27 1 0.0.0.1 64.65.76.96/28 1 0.0.0.1 anunu2> list ospf send OSPF Send Policies: Source Address/Mask Action ANY 000.000.000.000/0 Do Not Advertise LOCAL 064.065.064.000/18 Advertise anunu2> list ospf int OSPF INTERFACE TABLE IfIpAddr/IfInd AreaId IfType AdminStat IfState Metric 64.65.64.36 0.0.0.1 BC ENABLED OtherDsgRtr 1 anunu2> show ip network backbone SHOW IP NETWORK backbone SETTINGS: Interface: eth:1 Network Address: 64.65.64.36/25 Frame Type: ETHERNET_II Status: ENABLED Reconfigure Needed: FALSE Mask: 255.255.255.128 Station: 64.65.64.36 Broadcast Algorithm: IETF Max Reassembly Size: 8192 WAN Type: N/A Remote IP Address: 0.0.0.0 IP Routing Protocols: OSPF IP Routing Metric: 1 RIP Interface Export Metric: 0 IP RIP Routing Policies: IP RIP Authentication Key: - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.

(usr-tc) v.92 info
by Charles Sprickman 05 Sep '01

05 Sep '01

Howdy, While browsing about for more info on v.92 on the consumer side, I came across this. Commworks just isn't faring well here. Cisco is already shipping code??? http://808hi.com/56k/v92s.htm And I assume we're still at a point where quads will NOT be supported? Are there any other catches, like "you must buy hiper nmcs to load the new code"?

(usr-tc) filtered packet logging
by Mike Andrews 04 Sep '01

04 Sep '01

Sorry to interrupt your regularly scheduled 3Com bashing, but: Anyone had any trouble getting logging of filtered packets to work? I've got packet logging set to "all", size 80, but don't get anything logged under ARC 5.1.99 code. This used to work fine... I know I have to be missing something really really obvious here... but I haven't had to touch my ARCs in so long I can't remember. (Not having to touch them is a good thing, of course... it means they work...)
