I'm running (C7200P-ADVENTERPRISEK9-M), Version 12.4(24)T4, RELEASE SOFTWARE (fc2) on a Cisco 7204VXR (NPE-G2). Currently, the router has about 200 VLANs configured on dot1q subinterfaces.
Now, the router hangs everytime we try to add a new Vlan.
Is there a well-known bug with the IOS version?
we have 2xNexus model 7010 (let's call them Nexus1 and Nexus2) connected via VPC to a couple of catalyst 6509 switch.Trunking has been enabled on the port-channel defined on both Nexus allowing some vlans.Below the config applied on both port-channel interfaces on both Nexus which are members of the same VPC number: [code]
supposing I'd need to remove some vlans from that trunk (e.g. vlan 100,200 and 300) using command "switchport trunk allowed vlan remove 100,200,300" and that I'll run that command on Nexus at a time (that means there'll be a condition for a short period of time where Nexus1 has removed vlan 100,200 and 300 from the trunk, while Nexus2 is still carrying those 3 vlans on its port-channel which is a VPC member) , could it cause any VPC inconsistency condition suspending VPC interfaces and therefore affecting the service for all remaining Vlans or only Vlan 100, 200 and 300 will be suspended when that condition will be detected?
I have some Cisco 1240 Access Points which are not centrally managed. I want to add 802.1Q trunking so as to be able to provision a guest VLAN. But a trick is that these APs are in some very high ceilings. I would like to provision the new trunking and guest VLAN without having to remove them from the ceiling. Someone suggested I just make the native VLAN save as existing and make the port to which attaches a trunked port. But when I did this I lost connectivity to the Access Point. Access came back as soon as I made the switch port an access port. how I can add the trunking and guest VLAN without having to get into the ceilings to remove them and configure them via console or other?
View 2 Replies View RelatedI have trunk etherchannel ports 47,48 which both have Vlans allowed on trunk 70,71. Everything works pretty fine. Now I am trying to add a new VLAN 72 to these ports.
conf t

switchport trunk allowed vlan add 72

So far so good. But when making the same command for port FastEthernet0/48 my switch stuck.
I need adding a vlan to the trunks bundled in port channel. I know how to add v lans to a port channel with Cisco IOS but with CAT OS.
I have 2 ports bundled to form ether channel in switch which is running CAT OS. There are already few v lans allowed in the trunk of each interface. now I need to add one more v lan.
For Example:-
v lan 135 needs to be added in addition to the existing v lans.
clear trunk1/2 1-112,115,117-134,136-4094
set trunk 1/2 on dot1q 113-114,116,135
and similarly on the 2nd interface
so if I add vlan135 to the trunk one after another will it cause any service disruption?
I have a 3750 as a core and have a series of HP Procurve switches that are daisy chained using one port. I have two vlans on the port now (6 &9) and everything works fine, all switches communicate and end devices on the switches are also talking. There is a requirement to add a device towards the end of the chain which requires it to connect using Vlan1. Once I add Vlan1 to the port onthe 3750 I lose connectivity to all the HP switches.

so i put the command

loopback internal
as soon igave this command, CPU dropped down to normal. Whats the deal here? now i need to activate the circuit on this POS interface, but as soon i remove loopback internal command , CPU shoots to 100% Although CPU sorted dont show any process causing it.

Both outside interfaces of 7204 gateways are connecting to 7609 with different public ip block.I used VRRP for my internal nework and failover have been tested working.Even tried to remove link of 7204-A and 7609, the failover works perfect.But somehow we're facing a problem:
- If I shutdown/ remove the link between my 4507R-E and 7204-A (primary gw_higher vrrp priority), vrrp redundancy/failover still works but internal network's internet connection goes down.
I asked our ISP and the route commands they put in their 7609 are as of follows:
ip route 3.8.8.0 255.255.255.0 3.4.4.4 name TO CUSTOMER LINK 1
ip route 3.8.8.0 255.255.255.0 3.3.3.3 2 name TO CUSTOMER LINK 2
And if they're trying to use Reliable Static Routing Backup Using Object Tracking, the internal network's internet connections is intermittent....alternate 4 ping reply and 4 timeout.
Note: IP used are sample only
When the router boots up, the boot loader keeps telling me it does not recognize the card and wait until it fully boots to see the revision on the card, but I can not see the revision on the card because it is unrecognized.
What boot loader I need to get the 7204 to recognize the card?

I am seeing packets being ignored on GigabitEthernet0/0, but can't find any reason what the reason can be for that. So far calculated that about 3% of the traffic is being ignored. If it was caused by shortage of input buffers, I would expect to see increasing counters somewhere at no_buffer, but that is not the case. The average txload and rxload on the router is low all times.

I have some issues with win 7 64 bit pro. I have 3 computers on a cat 5 wired home LAN using a DGL-4500 router and in yhe same homegroup. All are gigabit capable. 2 are regular PCs, one is an HTPC. All have the latest drivers.1) File transfers never exceed 12% of the network capacity.2) If I transfer from computer A to computer B's public folder, I can transfer 1GB in a few minutes. However, if I attempt to copy/paste a file from Computer B's public folder to computer A, computer A takes forever "discovering" the file, then gives some absurd transfer time, say 11 hours for the same file.3) If however I go to computer B and paste the same file into Computer A's public folder, the transfer takes only a few minutes.
4) If at any point during scenario #2 I right-click B's public folder from A during a transfer, I get the spinning circle forever which 90% of the time results in Explorer hanging and requiring the process to be killed/restarted.

View 19 Replies View RelatedI'm using a Cisco 2821 router to provide temporary Internet access for a private network of about 300 users for a conference at a hotel. The hotel has provided me a public IP address for the WAN side. On the LAN side I have a 10.x.x.x /8 subnet with the router providing DHCP and NATing (overload) across the WAN interface.
Users can pick up an IP address and access the web. Light web pages such as Google tend to load without issue, however if a user does something that takes more time, such as streaming a Youtube trailer or opening an RDP session, the connection will freeze.
It doesn't appear to be related to bandwidth availability. Pings return on average 10-15 ms. However, I will get a request time out about every 10th continual ping. Steaming video will load about 4-6 seconds worth of data, then will appear to freeze without dropping. Doing something like speedtest.net will send a large amount of data then will hang, without ever ending the conversation.
This doesn't happen when I plug a laptop directly into the hotel public Internet line. They also don't have issues with their network similar to this.
I do not have any ACLs, etc. loaded. The router is basically wide open as far as I can tell. I don't see the router resources getting used much at all.

Unfortunately that's about all I can do - i try to terminate the Auto-install script but even pressing the Enter key has no effect. I can ping the 2504 but HTTP just times out. The console cable and terminal software are fine (I use them daily on a number of Cisco devices). I have done a factory reset but the same thing happens.
So, I'm thinking the unit needs to be RMA'd ?

I have a 2911 router hanging/freezing at random times, could work fine for a week then crash, or sometimes, could only go a few hours, completely random with timing. The onyl fix is to manually pull the power and reinsert.When this happens, all services/access stop working, including nothing on console access.This was on 15.2.1.T1 which im aware, has a few bugs, so i upgraded to 15.2.1.T2.The issue continued, so I swapped out the 2911 with a brand new one. The issue is still present.
One interesting thing, is when the router crashes/freezes, all lights appear to remain on working as usual, but when i unplug any of the ethernet links, the lights still continue to remain flashing and on for the ethernet LEDs, even once i have fully removed the cat6 cable.
I'm using two WRV210 Linksys Cisco Routers to create a tunnel between two places with a pppoe adsl internet connection.I made several tests with new 2.xxx and old 1.7xx firmware, and nothing changes.Try to reset to factory defaults, and nothing changes.I have two problems:
1) The router crashes after a time working, usualy around 24 hours, sometimes more, sometimes less. The lights still flashing, but nothing happens, no VPN traffic and no ping response from the router, and of course, no internet access. I could see just that the router works a bit hot, but, I think that is normal.
2) The VPN IPSEC was configured, and both configurations are identical. All value are the same, I am using the dyndns service. So, the VPN quickly connects and I can ping and access remote computers. Windows Folders, VNC, IT'S REALLY WORKS FULL. WORKS REALLY FINE. PERFECT.
BUT, when the router crashes, as I've told on problem 01, after remove the power cord and insert ir again, the VPN don't reconnect.On log's, I could see that it's say that has no preshared key. [code] But, it worked before. Nothing changes, nothing, the router just restarts. No configuration was lost, (I checked the VPN IPSEC TAB), but says that have no preshared key,The unique way to restablish the connection is go on the VPN IPSEC TAB, and change symetrical any configuration, as change MAIN MODE to AGGRESSIVE on both routers.So, now are as MAIN. Tomorow probably it will crash, so, I will have to restart both routers, and change to AGGRESSIVE. So, when it happens again, i will have to back to MAIN.
The firewall on my RVS4000 appears to hang when ever I use Netflix. If I disable the firewall and re-enable it it works for a while and then stops again. My IP address is in the Approved Client IP Addresses so it is excluded from the URL filtering and Web reputation rules.

I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
We have 6509 VSS with FWSM Module and we have created two context on it, one is INTERNALL CONTEXT othe is EXTERNALL Context? We have spanned various VLANS in switches and FWSM context level. All VLAN Gateways are configured in context level.
Activity description : We had planned migration of these devices into a new Datacenter, it was a planned activity. During migration of devices from one Dc to a new DC we broke the VSS and kept the primary running and removed the secondary switch and migrated this secondary to new DC and powered this device ON in the new DC and checked all the config was very much fine but this device was OFF network as secondary was brought to new DC just to limit the downtime during the primary switch movement.
During the activity ( Primary switch movement )We powered off the Primary switch and mean time before shifting into new Data center We had brought up secondary switch which was already existing in the DC was put live in the network and it was working fine without any issues.
Later we had moved Primary into new data center and tried to put into VSS with the secondary , during this period the secondary device into went into RECOVERY MODE and primary device was not responding and devices went off network and immediatly we removed the VSL link and brought up primary into production network without secondary online in the network ( Without VSS just stand alone switch ) network started working, but bringing up the primary we found that some of the VLANS in the FWSM was deleted and some VLAN had misconfiguration ( example : say original VLAN ip 10.200.112.1 has become 10.300.13.1 ) also some of the access list as well as SVI was deleted making configuration mismatch.
Wanted to know while syncronization b/n primary and secondary switch in VSS if we pull out VSL link would create this type of issues.
I have set up 2 DHCP pools and 2 VLANs (1 *the native* for data / 1 VLAN for voice). When I use the command "switchport voice vlan 20" the port disapear from the show vlan brief list. When I use the "switchport access vlan 20" it shows up in the show vlan brief in the correct VLAN and gives the phone an IP. I assume that using the access instead of the voice is wrong and the phones would not configure correctly. But when I use the access the phone goes to the next step and tells me the TFTP files are not found. Why does the port disapear from the VLAN list?
