It may hits the bug CSCsh54647 <http://cdets.cisco.com/apps/goto?identifier=CSCsh54647> : SIERRA - show platform hardware capacity multicast shows error Symptom: An error message, "mcast_hw_capacity_show:Error getting v6 data", is displayed when entering "show platform hardware capacity multicast" command on IP-Service and IP-Base feature set images. Conditions: - The device is running IP-Service or IP-Base feature set image. - "show platform hardware capacity multicast" command is entered. Workaround: None.           Action plan:   try the "show platform hardware capacity multicast" and then see if the error message will pop up or not. But if customer don't have IPv6 configuration, then it's just a cosmetic problem.  They don't need to consider it. Hope that helps. Varun Vasisth ... View more

personally i have never seen such an issue please let me know what IOS are you running on the switches when did you see this issue 1st time ? any changes made ? send me the port config as well for those ports Regards, Varun ... View more

format the flash then copy the IOS and change the boot variable. This should fix the problem. Regards, Varun ... View more

it should be pretty simple check :- http://www.cisco.com/en/US/customer/products/hw/routers/ps259/products_tech_note09186a00801fc986 Regards, Varun ... View more

I believe you have tried a lot of stuff, and honestly i have never seen any of them not working. Either you are missing something or you are doing something wrong. I would suggest open a TAC case and they will do it for you and if it doesnt work then you will get a replacement. regards, Varun ... View more

I would recommend using Mode "on" it works like a charm in every scenario. Regards, Varun ... View more

i am not sure i understood you correctly however, when we talk about HWIC module its completly layer 2 module which can be used only to add more switchports to the router. But when we talk about NME module its a complete switch in itself. It based on 3750 architecture and can do everything a 3750 can do that includes routing and layer 3 ports as well. Moreover you can stack it with 3750 to be used as a stack of switch. If by gig 1 you mean the internal link b/w 2800 and NME module then it has to be either a layer 3 link or it could be a trunk link so that you have communication b.w 2800 and NME module. Please let me know if you have any other questions. regards, Varun ... View more

Runts, FCS, Alignment errors are all related to layer 1.  These errors are commonly caused by duplex mismatch and sometimes caused by  bad hardware (NIC, cable or port) or the connected device sent out frames which is less than 64 bytes and/or with bad CRC. Check the configuration, if the port is set to 100/Full.  For the first step, can you please configure this port to auto/auto and then check  the port again ("show port " and "show config") to see if the  port comes up with half duplex or full duplex?  This result will let  us know if the port and the device connected to it are both set up correctly.

I understand that you require instruction on how to add a new cat3750 to an existing stack. First off, if a new switch needs to be added, it must have the same IOS image version as that of the existing 3750 in the stack. This avoids the version mismatch issue. To do so, the new switch to be added must already have the image loaded to it same as the ones on the stack. This link has all necessary procedures when managing switch stacks: http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3750/12220se/3750scg/swstack.htm One important note though, make sure the switches that you add to or remove from the switch stack are powered off. This is because: Adding powered-on switches (merging) causes the stack masters of the merging switch stacks to elect a stack master from among themselves. The re-elected stack master retains its role and configuration and so do its stack members. All remaining switches, including the former stack masters, reload and join the switch stack as stack members. They change their stack member numbers to the lowest available numbers and use the stack configuration of the re-elected stack master. Removing powered-on stack members causes the switch stack to divide (partition) into two or more switch stacks, each with the same configuration. This can cause an IP address configuration conflict in your network. If you want the switch stacks to remain separate, change the IP address or addresses of the newly created switch stacks. If you did not intend to partition the switch stack: a. Power off the new switch . b. Reconnect them to the original switch stack through their StackWise ports. c. Power on the switch.
