I just installed a HWIC-2T in a Cis co 3845 running IOS 15.1(3) T New build.The IOS self installed the port configuration including the command line "clock rate 2000000." I can edit everything but that entry using the CLI. When I enter the "no clock rate" it will not take in the running conf.
View 2 RepliesI'm having an issue that I can't quite understand. I set up a test lab to get familiar with EIGRP routing. I have a Cisco 3845-MB with 2 VWIC2-2MFT-T1/E1 cards.sh ip int brief shows UP UP status on all serial ports. I gave it an IP address but I'm having trouble pinging the serial interface IP. It's dropping pings to its own S 1/1/0 interface when pinging from console. I have known good T1 crossover cables 1&2 - 4&5.
Here is the "ip int brief" from 3845-MB
3845-MB#sh ip int brief
Interface IP-Address OK? Method Status Prot

GigabitEthernet0/0 unassigned YES NVRAM administratively down down
GigabitEthernet0/1 172.30.2.1 YES NVRAM up up
Serial1/1/0:0 10.3.29.2 YES manual up up
Right now it's pinging itself at about 60 -90% success rate... and I can't figure out why it's dropping any packets at all. I have other issues with in the lab as well... but i think this might be my "core" issue.To make matters even more "weird" I've tried two different VWIC2-2MFT-T1/E1 cards and I drop pings with both of them.

View 9 Replies View RelatedI have a host machine (Laptop, Win 7 Home Premium x64) running Windows 7 Ultimate x64 on VMWare Workstation 9. I've got this system set up for UMDF driver development, because I need a target machine to debug drivers on. However, because I'm developing drivers for Win 7 (x86 and x64), I cannot connect to the virtual machine on via a simple network connection. Connection methods are outlined here.
I have tried a few different pieces of software (mostly Eltima software), and have Google'd every combination of phrases that I can think of. I can't find any information on this anywhere. I don't just need to share data between the machines, I need a more "physical" connection.
Does any know how to do this, or if there's another (preferably more simple) way of doing it?

View 4 Replies View RelatedI have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.

As per my attached diagram, I have three switches (Cat 3560-E and couple of Cat 2960-G)
Each PC is on different vlan
PC -1 on vlan 100
PC-2 on vlan 200
I need to connect PC-1 and PC-2 to the server. Server has no fixed vlan and can be changed.
Restrictions:
1) can’t change PCs vlan assignment.
2) can’t add 2nd NIC in the server.
I’ve tried private vlan but it requires separate physical ports for host and/or community vlan and somehow it did not work. I could be wrong Trunking using dot1q enabled on port 2 on all switches and connection works fine (server to PC-1 or server to PC-2) by enabling switchport access vlan 100 or switchport access vlan 200. However I need port 5 on switch-1 to respond to vlan 100 and 200.

Vlan 900 is a VoIP VLAN
Vlan 999 is a NULL VLAN and is shut down:

The 6901 phone doesn't support multiple VLANs, so our configuration above does not work unless vlan 999 is turned on (not good security wise). We got the phones to work also by removing vlan 999 and switchport mode access.

solution that provides the discarding of data for the access VLAN, while supporting the VoIP vlan for this phone?
