    Different VLAN Interface on 2950

    Does this 2950 connect directly to the VTP server? If not is the trunk to the 6500 without the MSFC passing all Vlans on both sides of the trunk? What is the output of "show vlan" on the 2950? Do you see all of your vlans?

    Different VLAN Interface on 2950

    3. Are the trunking ports in the same Native Vlan? Normally this is the administrative vlan, which is vlan 1 by default.

    Different VLAN Interface on 2950

    I have two thoughts, 1. Is the 2950 in the same VTP Domain as the 6500 server? 2. Are both sides of the trunk configured to pass the VLANs you wish to use?

    windows recognizes my modem but no internet provider does

    The problem may be with standard. Prior to V.90 being ratified two standards came into play X2 and Flex. ISP's normally supported this by having one number for X2 modems and another for Flex modems. It appears you have a pre-V.90 modem. During that period some modem manufacturers offered...

    Depending on what interfaces the 4500 and which model of the 2500 series you have one of the following should work. Method 1 If each router has a serial interface connect them via serial cables. Make sure they are of the same EIA standard (ex. RS-232, V.35). One needs to be DCE and the other...

    Best CCNA Practice Test

    If I were preparing for a Cisco exam, I would purchase the appropriate Boson exam. I highly recommend them. I've heard if you miss a question, the new Boson's have links to Cisco's web site with information on the question. I have not confirmed this though.

    Hello, My goal is to connect my

    I should have asked this first. 1. What VPN client are you using to connect to your works VPN server? or Are you building a LAN to LAN VPN tunnel? 2. What address and mask is the VPN server issuing you? Your home address is 192.168.1.x. With a classless IP address there is no way to...

    Hello, My goal is to connect my

    The problem is with the subnet mask. Your home network is using a 16 bit mask. When your home pc wants to talk to your works private network, it believes its on the local wire and not on the otherside of the VPN tunnel. Therefore instead of encapsulating the packet and forwarding through the...

    Back to Back Routers

    Tattl - The bandwidth statement is not required nor does it affect the serial interface. The bandwidth command sets the bandwidth metric component for routing protocols which use it in its caculation. Programs using SNMP also use the bandwidth command. By default the BW of a serial interface...

    XP Professional no longer sees drive as valid drive

    Thanks for the tips folks. Scandisk found directory structure and free space errors. Volume status description showed healthy with no substatus info, also under filesystem it was blank. Free space 100%. I ended up pulling the data files off the F: drive via dos. Reformatted the drive and...

    Back to Back Routers

    Cable standards mismatch. One cable is RS-232 DCE the other is RS-530 DTE. You will need to procure either a RS-232 DTE or a RS-530 DCE.

    Tool for monitoring bandwidth I use is Multi Router Traffic Grapher (MRTG). Following is the link: http://people.ee.ethz.ch/~oetiker/webtools/mrtg/ As for utilization of the T-1 - Do you have link compression turned on? If not consider turning it on. Be aware you will need to do this to...
