    Cisco VPN client loses hostname, group in connection entry

    I've been getting many corporate laptops into the help desk with damaged VPN client entries. Every one I've seen still has a line for the connection entry (it was not deleted). However, the Host address (or IP), the group name, and the group password (and confirmation) are all gone. The...

    Multicasting on 2960 and 3750

    I have a package called MCHammer which can act as an mcast server or client. The server pushes packets, the client joins then listens, then reports all the packets. I put the server on a machine on an access port of my 2960 in vlan 99. I put the client on a machine on a different port also in...

    Setting up a 3750 as an mrouter

    I have a few multicast sources and clients sprinkled around the campus. I have Cisco switches (2950s & 3550s) for access all talking to the core 3750 stack. The IGMP snooping is enabled (this is the default) on all the access switches. No switch has been designated as the multicast router...

    Roaming mulitple VLANs using a 4400?

    I have 4 different subnets where our couple dozen lightweight WAPs (cisco 1242s) live. They all connect to a CIsco 4400 wireless controller. However, when I define each of the four WLANs (each connects to a different logical interface) I want to use the same SSID so users can roam. No, says...

    No SSID from my 1242s on a 4400.

    I've gone through the 4400 configuration guide and everything looks great. The radios are reporting back and I can see them from the controller. The 1242 WAPs can see each other since the automatic channel selection and power levels look reasonable. But no client can see any of my SSIDs...
