Hello, here are some answers to your questions: #1 What is ganed by migrating over from PPPoA to PPPoE and advantages if any? PPPoE induces slightly less overhead than PPPoA (except if you are running PPPoEoA) and does not require any ATM connections. It is thus easier to deploy. #2 Can you run both in Parrallel? Can PPPoA and PPPoE even exist on the same router? Yes, you can have both running at the same time. The only thing to be careful with is if you are running PPPoA and PPPoEoA (PPPoE over ATM) towards a specific customer, those would require 2 separate PVCs I believe. #4 IPv6 advantages? Our company although small is taking IPv6 very seriously. At the moment, using IPv6 only prepares your router for "the future". There are no yet any specific bonus to implement it apart being ready. #5 Caveats or Problems? Anything is possible ;-) ... View more

Hello Ronald, looking to the error, it could be linked to the following bug: CSCtl72890 duplicate of CSCtq05004    Dialer loses IP Address sporadically CSCtq05004 is currently not fixed. Though, with the description above, it is not enough to say for sure this is the issue you are facing. As this may be complex to resolve via the forum, it might be best to raise a TAC case for this issue. Things that could be interesting to log at the time of the problem is:      - debug atm error      - debug atm event      ((the above debugs could be enabled prior to the problem appearance and their logs checked at the time of the probmem))      - show atm pvc /    a few times in a row      - show dsl int atm ...     or     show controller dsl ... At the moment, what is the configuration used on the CPE ? Maybe the configuration could shed additional light to this matter. ... View more

What type of switches are you using ? You just need to make sure spanning-tree is properly enabled on each of them. Also, when you refer to the "orange" port, do you mean the color of the led for that particular port ? What happens if you check spanning-tree state on the different switches (show spanning-tree vlan ) ? Are you using any specific features on the ports used in the "triangle" like portfast ? Can you share the switches configuration and how they are interconnected ? ... View more

Mary, if the second interface has been in down state for some time, then we can indeed not blame it. This then looks like a software issue where either the interface or policy-map counter(s) are not updated properly. Now, there has been a lot of counter bugs (rate, byte, ... in policy-maps) and the software running on the router is quite old. So, I am inclined to suggest to upgrade it ;-) A quick search in our bug database did bring a potential match (CSCsw8274) where clear counters does not clear the policy-map counters properly. It could be partially related. So, at this point, it would be best to either upgrade the router or open a case with the TAC to investigate this further (though they would probably give you the same answer). Fred ... View more

The 878 has a built-in G.SHDSL interface so can potentially be connected to the DSL line directly. What is the modem doing exactly ? Does it have a DSL interface and an ethernet interface and bridge between the two or is it a router ? What is the status of the interface of the 878 towards the modem ? What is your current configuration ? Fred ... View more

Looking to the Gig0/2.501 configuration, I can see rate-limiting with drop exceed action. Could it be possible the drop counter got incremented by this rate-limiting configuration (before it was shutdown) ? If you clear the counters and check again the drop counter evolution, do you still see the discrepancy ? Fred ... View more

Hello, which version of Windows are you using and which Java version ? If you try to ping the different 15310, is that working ? Are you able to login at least to the GNE or is that failing as well ? If you can ping the 15310s or the GNE, you could try to start CTC using CTC launcher instead: http://www.cisco.com/en/US/docs/optical/15000r8_5/dwdm/procedure/guide/d85ictc.html#wp193556 The CTC launcher is an application you install on your local machine and which you can use to start CTC without the use of a browser.

hello, the interface drop counter should summarize all the drops recorded under the interface and all its subinterfaces. In this case, are there other subinterfaces configured under gig0/2 ? Can you give us the config of the different gig0/2 subinterface(s) ? Also which router is that ? What software version is it running and what type of module is housing gig0/2 ? ... View more

Scott, for such a problem, I guess the only way to really go down to the bottom of it would be to look to the problem while it is present. Should you see that issue again, contact the TAC and ask us to look to the 6500 live. Maybe the hardware programming for the GRE tunnel got messed up by the crash. Also, to be honest, 12.2(33)SXI is quite old and it is quite possible a later software could fix this issue.. Fred ... View more

Scott, answering why the GRE tunnels did not come up is not going to be easy with the available information especially that you have now cleared the problem. Were there any syslog messages at the time of the problem ? When you say the tunnels did not operate, do you mean you could not even ping the tunnel remote end from the 6500 ? Can you give more details about that problem ? Fred ... View more

Hello, Looking to the crashinfo file, we can see the following: Dec 25 18:12:57: %SYSTEM_CONTROLLER-SW2_SPSTBY-3-ERROR: Error condition detected: TM_DATA_PARITY_ERROR Dec 25 18:12:57: %SYSTEM_CONTROLLER-SW2_SPSTBY-3-FATAL: An unrecoverable error has been detected. The system is being reset. just before the crash. It seems the SP experienced a parity error and crashed. For such problems, it is usually recommended to monitor the SP as this could be a one time event. If it crashes again with the same cause, have it replaced. ... View more

Hello, to allow 1500 byte packets to be sent across the tunnel, you will either have to: 1) increase the MTU of the WAN interfaces (apparently not possible here) 2) You can also try to configure "tunnel path-mtu-discovery" under the tunnel interfaces and let them find the best MTU based on the path they cross or decrease the mpls mtu. Though, if you the tunnel MTU is decreased, that means fragmentation will occur. If applications are using the df-bit, you will then need to clear the df-bit for each packets entering the router. Which router/module/interface are you using here ? ... View more
