I'm afraid I don't understand your question, can you rephrase it? Usually, ISP's are authenticating users with a Radius server. Adding an attribute in the user definition has a minimal impact, I don't see how it can be a big overhead. Regards ... View more

Hi, Noise margin and attenuation are acceptable but far from being good (just for reference, noise margin, the higher the better, under 8 dB the line will start to flap. Attenuation, the lower the better, 40 dB means you are pretty far from the DSLAM). You can see that there are a few CRC and header errors. Try to monitor for a couple of days this output, to see if margin and attenuation are fluctuating during the day. If PPP goes down again, check if there has been a significant increase in the error fields. If that's the case, then the firmware upgrade can definitely help. 'Dialer persistent' is telling the dialer to try to be always up, no matter if there is interesting traffic. If PPP goes somehow down, the dialer should try to restart immediately, starting a new PPP negotiation. Hope this helps Marco ... View more

Hi, If I recall correctly, that firmware is optimized to work with BT DSLAMs. Perhaps you may ask BT directly for a copy of the firmware. However, from what you wrote it seems that the DSL layer remains up, and only PPP flaps. You should collect a "show dsl interface atm" to see what are your noise and attenuation levels, and if there are CRC and drops reported at ATM level. It is possible that the ATM layer stays up, but with several CRC's, causing PPP layer to come down. BTW, did you try to restart PPP without disconnecting the cable? for example, shut/no shut the dialer, or configure the dialer with 'dialer persistent' Regards Marco ... View more

Hi Bhavesh, for IP subnet sessions you need to be sure that the radius server adds in the access-accept a Framed-IP-Netmask attribute. ISG will match the netmask attribute with the subscriber's IP, and if it matches it will add that traffic to the single subnet subscriber. There is no special config required for TAL, just use source ip as identifier. You can also refer to this page: http://www.cisco.com/en/US/docs/ios/isg/configuration/guide/isg_acess_sub_sessns.html#wp1054603 Regarding the QoS, one approach will be to add timed ACL's directly in the MQC policy-map. You will have a single QoS policy with different classes, matching different times of the day. Another alternative is to implement the logic in your policy server, and push a new service with CoA at a specific time of the day. Marco ... View more

There are no official tools, but have a look at Dynamips: http://dynagen.org/ Hope this helps Marco ... View more

Hi Sandeep, the problem of Juan is that HWIC-2CE1T1-PRI is not supported on 2801 (as per documentation), so no matter how many DSP you are going to add, there will still be no PRI available. Juan, what is the exact requirement you need? Is the PRI needed for voice or for data calls? An example for voice calls can be: VWIC2-1MFT-T1/E1 - 1-Port RJ-48 Multiflex Trunk - T1/E1 + PVDM2-64 - PVDMII DSP SIMM with four DSPs However, before to buy any equipment, it's always better to double check with your local Cisco office. Hope this helps Marco ... View more
