I have a 2801 router that I am replacing with a 2911. I know the ports on the 2911 are Gigabits and the 2801 are Fe. I read where the IOS would not support backup and restore on each other . I am attaching a show ver on both routers. I need to know if backup and restore would work and or what other changes would need to get done.

We have recently implemented some QoS on our routers and i have noticed that the CPU usage has risen enormously as a result.
I checked the CPU Processes and found that the avg values are 50% usage. This seems rather high considering that only 75% of our edge routers have this feature enabled.
Our main router is a Cisco CISCO2911/K9 (revision 1.0) with 487424K/36864K bytes of memory. Our edge routers are either 2801 models or 881 models.
This is our first implementation of QoS and would like to ensure that it is working properly before implementing other QoS rules. Here is a copy of the config on the 2911 router:
class-map match-all Citrix
match protocol citrix
class-map match-all Print
match protocol printer
class-map match-all C-Coolingata
[ code]......
Here is the config on our edge routers:
class-map match-any Citrix
match access-group name Citrix-ACL
[code]....
As you can see we have different link speeds at different sites based on their size, location etc. How to be able to confirm that this config is correct?
Im using a 2801 router with a nat configuration.

I have a 2651 that has an adsl1-wic that I am using as my DSL router. I recently acquired a 2801 that I want to replace the 2651 with. I configured the 2801 the same way as the 2651 but on a reload I get the statement that says
Setup: New interface NVIO placed in shutdown state
When I do a show interface all of the interfaces show up except the NVIO and I don't have any connectivity to the outside world. I am using Nat since I have a /29 and using nat pool overload. What am I missing? I am running IPVOICEK9-M 12.4.25c on the 2651 and adventerprise 12.4.24.T on the 2801
I want to set up my LAN to have internet access via my 2801 router.The 2801 router is connected to my home ADSL router.Now do I just configure a 0.0.0.0 'gateway of last resort' on the 2801 router pointing to the interface leading to the ADSL router ?Therefore, all traffic from my PCs that is internet bound will head out to the ADSL router and onto the internet.

He was in middle of configuration, so now at present, only telnet is able to login on "R2>" user mode, enable password is not set, so getting "R2>en % No password set R2>" I have tried different terminal software but no output from Console Port, changed the Console Cables, replace with working console cables, change speed (baud) settings. Also tried to connect same console with "AUX" port and got same error mentioned above.

View 4 Replies View RelatedI have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
!
ip source-route
ip cef
!
!
multilink bundle-name authenticated
!
license udi pid CISCO3825 sn FCZxxxxxxx
!
vlan internal allocation policy ascending
[code].....
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?
How to replace a defective redundant sup. I read on several articles that inserting new redundant sup should not be an issue as the active sup will always send its configuation to the standby. We are running SSO on the Sup720. Should I switch it to RPR before I install the redundant sup? I read a case wherein they switched it to RPR from SSO before inserting the new redundant sup. My concern is the IOS mismatch since Cisco doesn't always send the same IOS on RMAs.What I am planning is this.
1. Save/Backup configuration
2. Remove the redundant sup on slot 8 (since it is a 6513)
3. Insert the new redundant sup on slot 8.
4. Check if all the configurations were synced from slot 7 to slot 8.
5. Copy the IOS from sup-bootflash to slavesup-bootflash. (if the IOS are not the same)
6. Check show bootvar to see if the boot variables are correct.
7. If bootvar is the same, reload slot 8 to boot the new IOS.
Is this a good plan or am I missing something? I am worried with this document if the redundant sup has a different software. If i insert the card in slot8, according to Cisco, it will revert to RPR. If slot 8 boots and it has a different OS, then slot 7 will switch to RPR even if it's active. Would I still be able to access the slavesup-bootflash of slot 8? Is it going to boot 100%? I read that doing a force switchover will cause a flip and RPR would cause the line cards to reinitialize and I don't want that. Well I am not going to do a force switchover since i want slot7 to be active and retain slot 8 as hot.
I am replacing a faulty sup720 on a 6513. It s the backup/hot not the active sup. It has the same IOS on it. Is it correct that all I need to do is remove the faulty and replace it with the new sup and do a wr mem? Fromwat I have read their should be no down time all connectivity should remain stable?

I have put the config on the new switches switches and I made it a server and used the same VTP domain and password etc and got the VLAN info ported over.Now I did this a while back and noticed the switches are in transparent mode with a revision number of 0, I need to set this back to server and swap the switches out but the revision will be lower than the client switches (around rev 200), what do I need to do?
View 7 Replies View RelatedI decided recently to switch out our border router (1841 12.4 advsecurity) with a shiny new 1941 (15.2 SEC/K9) as the CPU upgrade was needed.The core below acts as a VPN end point to various other remote offices we have, all of which have a similar network design at each end (and all entirely managed by me). All of these are still running 1841's with 12.4 advsecurity on them as well. These are all GRE tunnels with ipsec procection on them (not crypto maps). [code]
Everything else works fine (NAT, route-maps etc), it's just these IPSEC/isakmp tunnels that are not playing ballIt's definitely not an ARP issue (all arps were cleared) and ICMP appears to work fine (ie, I can ping the remote tunnel's public IP endpoint from the core using the loopback for that tunnel as the source). I am suspecting it's something strange with the stateful firewall config, but I did try and apply ipsec and isakmp-msft to the ip inspect list, with no success.
In my MDF I have a 4stack of the WS-3750-48P switches. Is it possible to replace one with a C3750X48PF-S with out causing any issues? Or would it be better to just have 3 stacked and trunk this one to the core 4506. Keeping in mind I bought this one to expand the port number for one of our remote offices.. I would hate to send them the gig switch when there isn't as much usage..Besides if I can get my CFO on this switch he might authorize me to replace the rest... He is reticent to believe it makes really all that much of a difference.
View 2 Replies View RelatedWe currently have an environment with a 4507 as the core switch connected to four stacks of 3750e's in the wiring closets. A pair of Nexus 5548UP's also hangs off the 4507, but at the moment more or less dedicated to a certain purpose..The 5548UP's have the L3 daughter card installed.
My question is: Can a pair of Nexus 5548UP's do a C4507's job? Would we be able to decomission the 4507 and replace with the existing 5548UP's + FEXes?
We are planning to implement the 6509-E with two Sup 2Ts and a few 48 ports switches. We also want to make this the router for our network and replace the 7206VRX.

View 5 Replies View RelatedI have two 3750X in a stack. Each 3750X has one 10Gb uplink to primary core1 and one 1Gb uplink to backup core2 configured in 2 etherchannel groups. The member switch has bad ports, so I need to replace it. I have spare 3750X unit. Is it possible to connect the spare unit to the stack and then move the RJ-45 cables from the member with bad ports to the new member? That way I can minimize servers downtime to just a few seconds..If that would work, then the last step would be to move the 10Gb networking module from old member to the new one, as well as the secondary PSU. Is it doable? Also according to the documentation, all I need to add new member is matching IOS version, correct?

I have two 3750G switches stacked together however it's not in a full ring configuration:
Stack Ring Speed : 16G
Stack Ring Configuration: Half
Stack Ring Protocol : StackWise
And as shown below it's obvious which cable is not working:
show switch neighbors
Switch # Port 1 Port 2
-------- ------ ------
1 2 None
2 None 1
It's not flapping - it's like the cable isn't there at all. I'm going to try reseating the cable in there and perhaps an all out replacement if necessary. My question - is there any threat of a reboot of the switch stack or of partitioning of the switch stack by trying to get the 2nd cable working?
The stackwise marketing info states that when a failed member is replaced with a new switch the replacement switch "gets the exact configuration of the old device". I would figure it takes a little more than just disconnecting and connecting a new switch in the same spot on the stack. doing this with 3750 family switches? What are the steps to prepare the stack for a new member? what steps need to be taken on the replacement switch before insertion into the stack to make sure it gets configured like the unit it was replacing?

View 2 Replies View RelatedWe have a Cisco 2911 router in our company. I didn't set it up myself nor I was involved. I only started working here recently, bit over 3 months ago. I have been given ongoing task which other IT Technicians been struggling for almost a year with a idea that maybe because I'm fresh person in the company I will find a original idea why could this thing not work.
Our router have a problem with blocking a single IP address, but not completely It's hard to explain but I will try my best. Company is hosting their website externally and accessing the host and FTP on the host on daily bases. It is important for the website to work on the internal network in company. It does work sometimes, but from time-to-time the website showing time-out error 118 on any point before Cisco router using both http and https, have tried putting just the IP address( doesn't matter is it on the general network or last ISA server on DMZ ). I am able to connect to the website using any of proxy gates but not directly to the website. I have also tested the connection past the router and I was able to connect to the website without any problems. I am also able to ping the host's address from the router and internal network.
I have eliminated the possibility of not correctly setup proxy or firewall on the network as problem also occur on the DMZ. I have also checked access-lists on the router and firewall rules for Any possibilities and I can't really see a way why would the router do this.
I am having 2911 router running with C2900 Software (C2900-UNIVERSALK9-M), Version 15.1(4)M5, RELEASE SOFTWARE (fc1)IOS and i have configured the following commands for eigrp

-network 10.20.0.0
-no auto-summary
It takes all 3 commands but when i check through show run command i am not seeing no auto-summary command.
how this switch module works in 2911 router? I have two 2911 routers in HSRP configuration for redundancy with crossover cable between switch modules. OSPF running on routers.If active router loses its power and then comes back again, it boots first, its internal link to switch module comes up and it starts to forward packets to switch module. The switch module starts to boot only after router is ready. So I have outage of about 3-4 minutes. For our real-time applications it is way too long.
any way to start booting of the switch module before router gets ready?I understand I can boot it manually, but it is only after router is ready. Only way to get around it I found is to disable internal link and use router interface to connect to the switch module.
I have a supervisor blade, (VS-S720-10G-3C), in a 6513 that is faulty and needs replaced. Do I need to replace the IOS on the new supervisor blade to make sure it is the same as the IOS image that is on the Active supervisor module, or will it synchronize automatically?
In the synchronization process, the active supervisor engine checks the standby supervisor engine run-time image to make sure that it matches its own run-time image. The active supervisor engine checks three conditions:
#
•If it needs to copy its boot image to the standby supervisor engine
#
•If the standby supervisor engine bootstring needs to be changed
#
•If the standby supervisor engine needs to be reset
I was reading the above documentation that mentioned the active supervisor should copy the image if it detects a newly installed standby supervisor blade with a different image, is this correct or was it referring to synchronizing the configuration file?
