Hi all
First i would like to say that i managed to put up a whole system and is working more or less fine except for DHCP service. DHCP is crashing once in 5 minute interval when CPE equipment is renewing IP address. Watchdog script is doing a job, but i would like to know is there someone experiencing
a similar problem. Funny thing is that some PCs are not crashing DHCP and some crashes it every time...weird.

It seems that in sql row in table dhcp_leases some strange input in column modem_macaddr (the CMmac address is completely twisted 88c1e20401c20000000000ÃââÃÂÃË) is crashing a DHCP. One more thing when an CPE equipment asks for IP address this is the ListMessage dhcp. What could be the cause of different modem address eery single time

and the cmts shows correct values
CMTS#show cable host so.me.ip.2
CPE MAC ADDR -> 0008.0dd3.d9fa
CPE IP ADDR -> so.me.ip.2
CM MAC ADDR -> 0018.c019.f088
CM IP ADDR -> 10.3.1.8
CM PSID 1
Maybe there is a fault in CMTS configuration or IOS version
That code your running on the BSR1k OLDER THAN DIRT... you need to upgrade. what the % or delta of free cpu?
what is the lease time on the modem and cpe from the dhcp server?
Also seen someone who has a BSR2k on this post. Same questions for you as well

hi,
i have similar problem, but crash whole cmts /bsr2000/, online on CMs is blinking and dont get ip from dhcp server. but other cmts uses same dhcp server - is OK. i did update boot rom and firmware and same crashes happen. after reload cmts everything is ok, until next crash.
what kind of firmware are you using?

hi,
what kind of docsis are you using? and what types o modems?
Modems are motorolas 5100E SurfBoards, and docsis server is docsis server 2.0.4 :)
miha wrote:Modems are motorolas 5100E SurfBoards, and docsis server is docsis server 2.0.4 :)
ok,
and bsr is switched to eurodocsis or american docsis? i think that your firmware is VERY old. last version of firmware is 2.01.11P01, it is from 3/07 i think. contact your support for new one.
Okay, i have acquired a newest version and tests will begin. As of euroDOCSIS or DOCSIS in motorola documentation is stated that eurodocsis should be triggered with RDN(config-if)#cable downstream 0 annex a but it seems that my motorola doesnt have that option. Either way it must be configured in EuroDOCSIS so please tell me if how to enable it

hello,
check > show controllers cable 0/0 downstream , for configuration of your DS.annex A is eurodocsis, B is docsis.
i think that it is no possible to assign if cmts must be euro or american.on bsr2000 it is possible, but b1k not.
