Cisco WAN :: 3745 / Migrating Configuration To New Router With Different IOS?
Sep 28, 2011
One of my clients has an older 3745 running IOS 12.3 and we are looking at replacing it with a new 3945 that runs IOS 15.0. This router is also configured with CME. Is it possible to migrate the current 12.3 config to load on the new 15.0 IOS? This will be my first encounter with 15.0 so I don't know what I am up against at this time. I am just hoping I don't have to retype all the ephone config, dial-peers, etc

I'm trying to migrate the running-config from our old 3725 router to our new 3945e router. Almost all of the config is copied over except for a few lines that come up as unrecongnized commands. So it looks like these commands were either removed or changed to something new.

I am migrating my PIX configuration to ASA 8.4(2) with my old nat configuration.I don't want the traffic match ACL inside_outbound_nat_acl from inside interface with NAT [code]
when I configured "any" in "nat (inside,any)", I cannot type the "route-lookup" command but when I change like "nat (inside,outside)" then I can type the "route-lookup" command.so what's mean of "any" in this command?

migration of an existing Sup720 configuration to a new Sup2T. At present we have a Sup2T chassis in the lab running 15.0(1)SY1 and a production Sup720 chassis running 12.2(33)SXI5.I've taken a copy of the production startup-config, renamed it to 'startup-config-BGFL_6509_MBAS-020712' and copied it to the bootdisk (and slave bootdisk) of the new Sup2Ts.I've then added the command 'boot config bootdisk:startup-config-BGFL_6509_MBAS-020712' in an attempt to boot from that config and have the Sup2T migrate it to the new config standards (particularly from a QoS perspective as mentioned here :[URL]

I just got my PIX515e configured and thought I had it working correctly, but on my 3745 router, the line protocol is down, I've looked through the configs for bot the PIX and the 3745 and can't seem to figure out why I don't have access.
Pix515E config:
pixfirewall# show run
: Saved
:
PIX Version 8.0(4)32

hostname pixfirewall
domain-name home.jkkcc.com

I am in the process of migrating my config from my PIX running 8.0(4) to my ASA5520 running 8.2(1). I have converted the config so that it is ready for the ASA. I noticed the "boot system flash:" and "asdm image flash:" command references the old PIX files. Do I need to update these or will they be updated when the ASA reboots with the new config?

There is no special requirements, just need new hardware with some reserve availability. As for now it's 3745 EOL and I assume to use 3945.

Have an ADSL router (887) at a site which has a GRE tunnel to to a 3745.The GRE tunnel is setup with default ip mtu of 1476.If I ping from the 3745 to the ADSL router (or in the reverse direction)with a packet size of 1500 bytes this works fine.However if I ping from a router (R1) that is directly connected to 3745 to the ADSL router with a pkt size of1500 bytes then the first ping succeeds while the subsequent pings fail.Pkt sizes less than or equal to 1476 work okay.Pinging between R1 and the 3745 with a packet size of 1500 bytes works fine.If I set the tunnel ip mtu size to 1500 bytes then it works.This is obviously something to do with fragmentation, but I don't undertsand why itdoesn't work with the default mtu set to 1476.

I have a subnet (vlan 104) working great across a WAN. At site 1, Router A (3745) has the L2TPv3 tunnel configured while Router B (7204) has a routed interface on vlan 104.
The only thing router A is doing is the tunnel, so I'd like put the tunnel on Router B and eliminate Router A.
The trouble is, when I move the configs to Router B, the tunnel comes up, but the far side does not receive traffic over the tunnel.
Router B shows sending and receiving packets (per the 'sh l2tun session all' command). The far end router shows sending packets but receiving 0.
Is it a problem to have both the vlan 104's L2TPv3 xconnect interface and the vlan 104's routed inteface on the SAME router?

I am really new to this and studiying so I know that I am doing something dumb. Anyway, I purchased an ASA 5505 and placed it between my Cable Modem and Cisco 3745 router. The outside interface on the ASA is dhcp, the inside interface is 192.168.100.1. The outside interface of the 3745 is 192.168.100.2 and the inside is 192.168.1.1. The VPN pool is 192.168.200.10 - 192.168.200.10.
Here's are the problems...
1. When I establish a VPN session to the ASA, I can ping and access any resources dierectly connected to the ASA's interfaces and on the ASA's internal 192.168.100.0 network. However, I cannot access any resources behind the 3745. I cannot even ping 192.168.1.1.
2. Although I believe that I sent up split-tunnel, I cannot U-Turn back to the internet once connected to the VPN.

I need to make sure I have a router available to work with DS3 circuit on remote site. A remote field technician tells me there is a 3745 router with "HSSI" and external Adtran CSU/DSU available. Is that an indication this can work with DS-3 circuit?Which specific Adtran CSU/DSU do I need in order to make it work with DS3?

I've came across a very odd topology to deal with where everything is connected to everything, without proper utilization of VLANs.
- I've an L3 SW and a 3745 RTR at core
- Both are carrying same subnet to an L2 distribution switch that connects server farm within the same subnet (i.e. 1.1.3.x subnet)
- The L2 switch works as a passive switch, hence another network say, 1.1.2.x has been plugged into it as well.
- This L2 switch extends to other switches without configuration of any VLANs or STP and distributes 1.1.3.x network.
Periodically and unexpectedly, the router starts hanging and utilization goes beyond 80%, and there's nothing at all that is observed in "sh proc cpu" to be eating router resources. Its quite difficult to observe the pattern, as its random.

I am having a problem getting serial interfaces to show up with a NM4A/S card in a 3745 router. It worked at first but now the serial interfaces don't show up in running-config but show diag shows the card is present but says "Port adapter is disabled deactivated". I have tried the card in 3 different slots and of course turned off power when moving card around (left power cord in for grounding). Again, it was once working (serial interfaces were showing up in running-config) so if I damaged the slot somehow, however I was very careful when seating card. Have been searching the learning network and google for days now to no avail. Have tried to find something similar to the card type command thinking the port adapter needs to be activated but have not found any documentation about that. Hope card isn't bad all of a sudden but really don't think it is since it worked before and it seems to be recognized just not showing serial interfaces in running-config/sh ip int b (on ios/cli). Really think it's something along the lines of activating card, but not sure.

I am almost new to the networking field, hence I might have lacking some basic knowledge. I like to know the impact if the ground of any router get disconnect. WIll the router stops work? We have two peripheral router in my organization, both are connect with the MPLS cloud through the MUX. One router (3745) have ground connection, where as the other (3845) don't. Recently the 3745 router start generating CRC error on the WAN interface. Once we remove the patch cord connecting with the MUX for loop test and reconnect later, the interface did not come back again. FInaly someone advice me to check the ground connection. I found it was loose. Once I fix it properly and reboot the router the interface become up. The person told me that some cisco router send the reference signal through the ground to the MUX connecting with it, if the MUX and router failed to exchange the reference signal the router will not work, is this true ?

We are pulled the plug on our PIX 501 as its not letting us use all 100Mbit that our cable provider is now piping to us. I read the conversion guide but it made no mention of the 501's. Only the 515's or newer.The ASA5505 is putting up a little bit of a fight (This what I get for failing my CCNA??)After refusing to configure the LAN ip address to something other than what it was shipped with, I broke down and connected to the management console and forced an IP address on the LAN side. Now I reset my default config and everyone can get on the internet.Until the ISP cuts you off because you forgot to set your static IP. Oh, and by the way, they dont support Cisco gear.
When I attempt to assign the IP to the outside interface, it accepts without a hitch, but everything grinds to a halt. I cannot have this, as I have off-site users that operate with dedicated ports using Remote Desktop. I've attempted to set the IP via both ASDM and management console. I've tried setting a static route, but that doesnt give me any love either. Im running ASA Version 8.2(1) and ASDM Version 6.2(1)Once I get the static IP set and working properly, I can tackle moving the port configs.

I need to connect site to MPLS provider and run Cisco GETVPN.Problem:I have been browsing Cisco Feature Navigator Tool and to my surprise when I enter "platform:3745" I can't find an image compatible with GET VPN. there is no workaround (image) I can run GET VPN on 3745? I need IP routing (BGP, OSPF) as well.

I need to migrate DFM alarm settings data from LMS 3.1 to LMS 4.2.3 and I want to use this method, [URL] , to extract the data from 3.1 and then inport it into 4.2.3.
I successfully performed it for IP settings, it was easy since the data format was the same.
But the format differs quite alot for Interface and Port data, here is an example:
export from LMS 3.1
IF-hostname/17 [Gi0/0.524] [10.55.254.3]; INTERFACE:;IF-hostname/17; MANAGED_STATE:;EXPLICITLY_UNMANAGED
export from LMS 4.2.3
INTERFACE:IF-hostname/17 MANAGED_STATE:MANAGED GigabitEthernet0/0.524
It looks like I have convert interface names, sort and delete stuff to make it look the same.

I have recently migrated from a PIX 515e to an ASA 5510. In the main this was successful. However, I have a number of L2L VPN's (all connecting to Cisco PIX 501 or 505). The majority of these VPN's are working fine. However, I have a couple of VPN's that are causing me a problem. It seems like the tunnel is established for anything between 10 minutes and 4 hours before going 'down'. I cannot initiate the tunnel again from the hub end (ASA 5510) of the VPN.However, if the remote end reboots the PIX, the tunnel is re-established.The ASA is running 8.3(1) and the remote PIX's will be running various versions of code but will all be 6.3(x). The strange thing here is that the majority of the sites are working and the config for each tunnel is identical other than the access-lists for interesting traffic and peer address.

for testing purposues i wanted to exchange a running ASA 5510 with a ASA 5505. I included the running configs from both the ASA 5510 and the new configured ASA 5505.
On the running ASA 5510 there is:
one interface for WEB
static IP xx.xxx.xxx.178
route 0.0.0.0 xx.xxx.xxx.177

I currently have the following set up (excuse my quick drawing):
--------------Vendors VPN Router----
| ------Cisco 3000 VPN------ |
| | | |
Private Network-------ASA5510---------Pub Switch------Cisco Router 2x T1
I've been tasked with migrating to the new ISP, which provides us with Cisco ME-3400E switch and /26 public subnet. I currently have 15 static NATs and 14 L-2-L VPN tunnels configured in ASA. Is there a way to configure additional Outside int on ASA and use it to migrate the existing VPN tunnels and static NATs? I'm trying to avoid downtime and hope to do it step by step. I'm thinking about adding additional Public switch, so I can also migrate vendor's router and VPN concentrator, which need to be in parallel to ASA. Assuming that this is possible I'd would like to do the following:
1.Configure and connect additional Outside Interface on ASA - public IP address and ACLs
2.Connect it to additional "Public switch", which would be configured with public IP address and connected to new ISP's Cisco ME-3400E.
3.Migrate my VPN tunnels and static NATs.
4.Migrate vendors equipment/VPN concentrator
5.Update my global NAT pool
6.Shut down old ISP

I have NCS 1.0 with 100 devices support license installed. Now knowing it has reached end of sale, and also for the fact that Prime does cover devices like routers, i went ahead to the upgrade path via PUT (Product Upgrade Tool). Finally I received an email (OBA) advising my order is ready. This email included two items in the shipment,
L-N-PI12-100-M=
NCS 1.0 to Prime Infrastructure 1.2 Minor Upg 100 Device
L-PILMS42-100-M
Prime Infrastructure LMS 4.2 - 100 Device Upgrade Lic
When i click to the link in the same email to download the license, it only shows me one file which is L-PILMS42-100-M I tried using this file and installing on the NCS1.0 but it gives me error that this file is not a license file. The license name suggests me that it is not the license to be installed on the NCS. The file should be L-N-PI12-100-M=

we've got a pair of old 3745's that are getting upgraded to new 2911's, and I'm trying to run IOS 15.2 on the new routers to get them most current before going into test and production use.The routers are doing BGP, IPv4, and HSRP, and I'm trying to put one in at a time as to not have to big bang everything at once. I'm putting the one that matters least in first, and basically using the same config as the old one, which was running IOS 11.
I was using "no ip mroute-cache" on ethernet interfaces, and it says that command is deprecated and I should use the MFIB commands instead. Darn if I know what that means, I believe it was set up so the ethernet interfaces had IP multicast fast switching disabled, which was set up by our vendor 10 years ago so I'm not sure if it matters. It would seem logical to me this would have an impact on HSRP and speed of failover. Does this matter, and if so how in the world do I do this with IOS 15.2?The second one is the use of "no fair-queue" on our serial connection for a T1. This command isn't there either, and I'm not sure if I even need to bother on this. It was set up on the old router on a T1 Frame Relay circuit.

I am replacing an old 4400 series WLC running version 4.0.179.11 to a new 5508 WLC running version 7.2.110.0.
We currently have 70 x 1131 Access points on the 4400 WLC.
With this upgrade, do i need to upgrade the old 4400 to version 6.0 so the AP's get an up to date IOS or can i directly migrate all AP's over to the new 5508 without any version incompatabilities on the AP's?
I am abit worried that the AP's are running a very old IOS on the 4400 v.4.0.179.11 to go straight to the new 5508 v.7.2.110.0.

I have a situation here where after migrating from PIX 6.3 to ASA 8.4, VPN connection from window server 2003 and 2008 fail to connect. Strangely, win7 or win 8 works perfectly well.
It failed due to
reason=DEL_REASON-IKE_NEG_FAILED
The diff we can see is win 7 is 32 bits and the server client version is 64bits.
