Cisco WAN :: 2851 Router Showing Error For Peer Set Configuration
May 28, 2012We have Cisco 2851 Router part code CISCO2851-SEC/K9 facing issue while set peer configuration, issue description below.
Issue:We are facing the problem while configuring set peer as when we try to this we face error like 'unable to set peer.maximum numbwe of peer (40)exceeded'
We suspected the IOS issue hence we have gone for IOS upgrade for this Router but this error is still coming while configuring set peer.

Cisco Firewall :: 5540 - Active / Standby ASA Failover Configuration Changes?
May 15, 2011I have 2 ASA 5540s ver 8.3 in Active/Standby state.I am considering a future hypothetical situation where I might need to rename interfaces or reallocate redundant interface groups. Doing so obviously has a major impact on the current primary configuration. My goal would be to minimize or eliminate network downtime during the interface changes.
I am wondering if it is possible to force the secondary ASA from the standby to active state.Then temporarily disable failover on the primary unit.Make the interface changes on the primary unit Then reactivate failover on the primary unit Force the primary unit back to active and secondary unit to standby My new interface configuration would then sync from the primary to the secondary.
I believe this would work but must ensure that the secondary ASA can function as the active unit while the failover is disabled on the primary unit. Is there a set length of time the secondary unit can remain active without a failover peer?
see issues with operating the secondary unit in this manner while making changes to the primary unit?

Cisco Firewall :: 5510 Setup In Active / Standby Failover Configuration
May 8, 2012We have 2 ASA 5510's setup in an active, standby failover configuration. When the primary fails over to standby, the 3rd party cert does not failover to the standby ASA. The users then receive the CERT missing, invalid message and have to select yes, no to move on. This does not occur when the primary is not in failover mode. It is my understanding that failover fails over certs but in our case it does not apper to be working correctly.
View 1 Replies View RelatedCisco Firewall :: 3750s / Trigger Failover Without Standby Address Configuration?
Nov 13, 2012I am trying to establish EIGRP neighborships with my inside switches (3750s) over the "Internal" interface, shown in green. The outside interface is g0/0 and don't worry, I've ensured EIGRP is not running there.The problem I'm having is that I need to monitor the "Internal" link so that if it goes down, the ASA triggers the failover to the secondary firewall connected to the other switch. I was told that the "secondary" keyword was what enabled this:
interface GigabitEthernet0/1
nameif Inside
security-level 100
ip address 10.10.2.2 255.255.255.0 standby 10.10.2.3
This is fine since I am able to compare this config to the firewalls that are currently in production elsewhere in the environment and this is what's in use there. However, in order to run EIGRP all the way to the firewall and not rely on something else like HSRP for the inbound traffic, I'd like to run the corresponding links (Gi1/0/22) on the inside switches as routed ports (no switchport) so that I don't have to establish neighborships with SVIs or something like that. I want the routing to be done directly to the port, leaving the interfaces for failover and our DMZ set up as switchports, since those can be layer 2.It's saying the Internal interface has failed now, probably because it cannot send hellos through this, since it's a routed port on the switch side. I'm wondering if this simply is an impossible design, unless there's a way to track this interface and trigger a failover if it goes down using another method.a method that allows me to track that internal interface (Gi0/1) and trigger a failover if it goes down.
Cisco Firewall :: Adding Failover ASA 5510 Back After Configuration Changes On Primary
Nov 28, 2012I had a working active/passive pair of ASA5510's, and then I had to do a rush firmware upgrade, but didn't have time to do it on the secondary at the same time. Now I have made config changes and upgraded the secondary firmware to be the same, and wish to know if I plug it back in if it will think the secondary has the "correct" config or if it will know that the primary is newer. I disconnected the failover cable because it was complaining about version mismatches constantly.
Is it safe to add the secondary back in or is it possible it will be declared newer and overwrite the config?

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.

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.
