My company is doing an nationwide upgrade of it's leased 2951 routers. For security sake I need to wipe everyone of them before being sending them back to the leasing company. I would like to somehow boot to a USB drive and call it a day.
View 4 RepliesI configure HSRP on Router 2951 as a primary router, and Router 2811 as backup router. But when I am switching off my Primary router the backup router is taking 2 mins to take over form primary router.

I have been researching this for an implementation I am doing for a client and was able to determine it was not supported with earlier versions of 5.0 when the FEX is connected via vPC as I described above, but I can't find anything related to version 6.0(1). I have done this for other clients with 5000 and 2000 switches, but I don't have too much experience with 7000 switches.

View 5 Replies View RelatedI'm trying to set up a 2951 with a 24 port switch module. I want the ports to act similiarly to the ports on an 881 router - where I assign the VLANs on the router and I set the VLANs to the switchport interfaces.I would like to be able to create the VLANs on the router portion of the 2951 and then, enter the switch module and configure the Ports to the VLANs but, how do I logically connect router to the switch? Is it an internal logical interface - meaning how are the VLANs getting from the router to the switch?

And I would like to ask some opinion on the best configuration for the above layout:
1. Configuration #1 - Using load sharing and automatic failover So I want to ask whether there's any link/url that provides details/guides on how to setup the load sharing and failover?
2. Configuration #2 - Workstations 1 - 35 will be routed through Line01 gateway and workstations 36 - 70 will be routed through Line02 As for this configuration, it's done now. However, I want to know whether there's any software (preferred web based application which allows me to change the gateway from line #1 to line #2 for all 70 computers instead of having to go to each workstation to update the gateway).
nyone know if "vpc-orphan-port suspend" works if i put on N2k interface. not the fex link. example i have fex 101 and i put on eth 101/1/10 will it suspend the port on N2K connected to secondary N5K when peer link is down?

View 6 Replies View RelatedI am designing a network for my client where I have to implement a 10 Gig end to end connectivity. The major factor of concern from my management is about scalability (space to include more 10Gig servers as the nodes grow up). I have suggested Cisco 5596UP with 2232 PP as this gives ample amount of 10Gig ports. The setup has to be implemented across 2 different datacenters located 40 Kms apart, connected with 10Gig DC Interconnect.
I understand that Cisco Nexus 2232 is a Layer 2 Only switch and would need to communicate with parent 5K switch very frequently. Is it necessary to have the 2K and 5K pair in the same datacenter or in proximity? Is it possible to have the SFP uplinks connected to the DC interconnect? Because we have two datacenters located 40 Kms apart and having 1*Layer 3 - 5K switch at DC A with Layer 2 - 2K nexus Switch at DC B will be cost effective. We do require more 10Gig ports and not much requirement on Layer 3 usage. What are the type of communication that would be much frequent between 2K and 5K?
Does the LACP will be supported on Nexus 2000 host interfaces when parent switch is Nexus 7000?

View 1 Replies View RelatedWe are planning on testing a new ISP provider in our company but we have the following doubt: This new provider is using a Optical Fiber line (GPON – PT Prime) for this new internet connection and we already have a Cisco RV220W router but they are not sure if that can be used, so they just informed that they a capable router is the Cisco 2951-SEC/K9, that they are selling of course. So our actual doubt is if the Cisco 2951-SEC/K9 can have some “extra” WAN configurations/authentications that are not available in our Cisco RV220W and that can implicate that we cannot use our RV220w router?
View 3 Replies View RelatedWe are a medium-large sized company with approx.100 offices located across North America. Every single office connects to each other and the data center via a DMVPN overlay network. The DMVPN hub router (Cisco 2951), R-Q9-1, is located at our data center and is the "workhorse" of the company. We also have a redundant hub router, R-Q9-2, at the data center with exact same hardware specs.
Each office builds an EIGRP Tunnel0 and Tunnel1 to R-Q9-1 and R-Q9-2 respectively. All data traffic flows over Tunnel0 to R-Q9-1 until it fails, at which point traffic starts to flow over Tunnel1 to R-Q9-2. This has been working seamlessly for last 1 year of implementing this design, until yesterday, when both R-Q9-1 and R-Q9-2 rebooted all of a sudden at the same time right in the middle of a production day. I confirmed there was no power failure at the data center. A show version of both routers gives me this:
R-Q9-1 uptime is 1 day, 1 hour, 24 minutes

I Google that error but can't find anything specific other than it's saying it's some kind of bus error. What I also found a bit off is the time it's showing on both routers' show version output (Sep 21, 2010 and Jan 10, 2012). Here are the current clock settings on both routers at the time of this writing.

R-Q9-2#sh clock *16:59:44.220 EDT Wed Oct 31 2012
I checked my Syslog server and did not find anything specific during the time of the crash, however, syslog was filled with errors similar to this one

I have never seen these errors before and all of a sudden they seem to have stopped since this morning.
We have a new optical fiber connection from a new ISP (only for Internet) and we found that our Cisco router RV220w won't work with this new connection because is not possible to add the V LAN ID 20 for the WAN traffic, as required by our ISP/connection. Now we would like to know what Cisco routers can support this feature and that can be "similar" to the RV220w or if there is another way to solve this problem and maintain our actual RV220w, because the features on this particular router (apart of the V LAN ID on Wan) are more than enough for us -
We would like to have a “simple” router and with firewall and VPN features as RV220w, because the one that our provider says that works seems to be too much for us Cisco 2951-SEC K9 – We are a small company with a network of around 10 computers and we only need some VPN connections for our sales companies in Europe and workers when traveling (3-5 VPN connections are OK).
I just got my first WRVS4400N v2.Nothing has changed, the definition of small business means there are USUALLY one office, and several people runs around thus the need of a VPN server sitting at the home office Router. I think most of us small business operators had wished for a connection away from office, NO REMOTE GROUPS, just clients on phone, or laptop. Using this connection to get to some files which isn't sitting in the cloud, or perhaps using it to hop over firewall restrictions that some overseas countries had imposed.
What you should have is a setting for Stand-alone VPN server, NOT Router to Router.. What you should have is feature that generates the various psk for different platforms. What you should have is made things simple, instead of these magicabbage which goes no where for the small businesses.Through out this thread the original poster is presenting the same problem, he and I don't have a Remote Group router to enter an IP address, tell us to use the QuikVPN client DON'T work, the Server isn't UP to begin with!Moreover, the VPN client installer on the this new v2 runs only in Win 2000 or XP??? What the (*&^! Doesn't seem like a large business like Cisco should have in their boxes.
How do I update the firmware on my N wireless router with version 2000? It says there is an update, but I can't update it with the one firmware update that's available for download.
