Apr 11, 2005I have a 2811 that I'm in the process of turning-up to support a 4xT1 using VWIC-2MFT-T1's. The question is how to "correctly" set clocking on the MFT's.
As is typical of the 2MFT's, as soon as a 2nd T-1 on a VWIC-2MFT comes up, I start taking "Slip Sec"s on the 2nd T-1. I have tried different clock source combinations, including "clock source line primary", various "network-clock-participate" (or not) combinations, and about a dozen other stab-in-the-dark configurations. Before I started playing with it, the slips were consistently every 9 seconds. After playing with it, I got them to every 18 seconds. But there shouldn't be ANY. So the question is what SHOULD the correct timing configuration be on that platform?
The VWIC-2MFT-T1's are in slots 1 and 3, so the controllers involved are 0/1/0, 0/1/1, 0/3/0 and 0/3/1.

Oct 29, 2012I understand that most of the cisco switches does not have a battery-supported system clock. The better solution is to setup the NTP server and let the rest of the switches to synchnorise the clock with it. How about cisco switch 4948? Does it have a battery-supported system clock?If the cisco switch 4948 is the NTP master, how I am going to make sure that the clock will not be reset after reload?

Jan 16, 2011I'm trying to get an HP laptop running Win7 to see a desktop running WinXP on my network (both wired and wireless) When I run the troubleshooter in Win7, it tells me "system clock does not match local time" as the reason. I have a Belkin wireless router attached to my cable router. I have updated the system clock via the internet on the desktop and checked the time setting in BIOS. These seem to match. I have googled around on this and can't find any accounts similar. My son's Vista laptop and the Win7 laptop have seen each other since day one. The laptop and desktop did see each other at one time, but the connection was lost after I went to a hotel and changed public network settings temporarily. I can ping the desktop from the laptop, but it times out when pinging the laptop from the desktop. I'm running an avast firewall on both, but can't see a problem there.

Cisco WAN :: Licensing For IOS 15.x On 2851 Routers?
Feb 16, 2012Do I need to obtain license keys/files when upgrading a 2851 to IOS 15.x? I'm getting a bit confused seeing the documentation that says 1) IOS has gone to a universal image and 2) that feature sets are unlocked based on the installed license.
I was able to download a feature specific IOS image for the 2851 and it did not bother me about licensing upon boot up.
I read one post on here that stated 2800/3800 series (G1) do not have to worry about the licensing piece and that it's just 2900/3900 series (G2) hardware that require it.

Cisco WAN :: 2851 - How To Route / NAT Based On IP With 2 WAN Connections
Mar 29, 2012I have a Cisco 2851 (with a 4 port switch module) that I am trying to set up with two different internet connections, and have it route traffic out to them based on the source IP. One connection is a 50mb Comcast connection, another is our T1 that our servers are hosted on. The goal is to guide server/phone system traffic to the T1 and have the rest default to the Comcast. I currently have the 2851 connected to our Layer 3 switch (Dell Powerconnect 6224) with a subnet created between them. Static routes have been created on the 2851 back to all of our existing subnets. Traffic flows internally without a problem between the subnets and 2851 (and vice versa). I set up the 2851 with route-map's in the NAT to control the flow of traffic, with the default route set to the Comcast connection. Default route works great, speedtest shows full speeds and everything looks great. The problem happens when I apply my route-map policy to the internal LAN interface with the ACL list of IP's that I want to guide to the T1 (with a next-hop of the T1's IP address). I tested some tracert's and pings from one of the IP's in this list and they would stop at the T1 modem and not go any further. I did a "show ip nat translations" and noticed that the "outside" portion (right half) was blank for every IP that was in the ACL or related to the T1. So my guess is it looks like this is not doing NAT for the T1? I double-checked that I had my "ip nat inside" on the LAN interface and "ip nat ouside" on the T1 VLAN interface and Comcast interface and they were there.

View 4 Replies View RelatedCisco Infrastructure :: 2851 Router Not Boot From CF
Nov 12, 2012I recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.
