Cisco Infrastructure :: Removing Unused Virtual-access Interface On 3725 Router
Sep 8, 2004
I had the 2 circuits go down at the same time from our ISP and I had to power cycle the router and when it came back up I went from VA # 2 to now VA 3#....I know what is what but it is confusing for my counterpart and I can not remove the old entry for VA#1 and VA#2. [code]

We have a 3745 LNS router, currently there are less number of users connected.when a user dials request authenticated and one virtual-access interface is formed in LNS router.Now the user is disconnected the vpn and connected to VPN again in this case, whether the user is connected to the same virtual-access interface which was assigned before disconnecting or different virtual-access interface is created.

According to the Installation notes for ACS 5.3 we need 500GB of storage for a working installation - if not it defaults to taking 60 GB of disk space for an eval version.

I have a frustrating issue with a dynamic VPN head end running IOS 15.2 on 2900's. I have existing keyrings, and isakmp profiles (both main and agressive) running. When I add in a new peer, by adding in a keyring prechared statement and a match identity in the isakmp profile, phase 1 biulds but phase 2 only gets right to the end and the Cisco side resets the connection because it did not get back a response to it's Phase 2 proposal.I have tried a number of soft clear commands to remedy this (I do have 16 other production tunnels I do not want to take down) and no avail. This is very consistent. We had this happen last week in the same manner, and the TAC finally said I must reboot the system. So I removed the cmap from the interface, and reapplied it (using notepad to do it all at once). All the tunnels dropped, and after a few manual restarts on the far end for thos etunnels that are tempermental, all tunnels came back up, including my new add.I have a pair of 3900's running 15.1 code in the US that terminate the same tunnels, and I can add and remove PEERS all day long without resetting anything. Could there be a more polite way of resetting what ever it is that removing the CMAP does to allow my new peer to get the full treatment here?
crypto pki token default removal timeout 0
crypto keyring Site-to-Site
pre-shared-key address a.a.a.a key lkdshjfhjkdsfkjfsjkddedswdes
pre-shared-key address b.b.b.b key lkdshjfhjkdsfkjfsjkddedswdes
[Code] .....
I just negate this and re-add and new peers start working.

I have five 877 routers connected to ADSL circuits provided by Vodafone. Each has a VPN tunnel back to a PIX.
Occasionally one of the sites will lose it's connection to the PIX.
When we check the log, we find entries like these:-
Apr 5 01:31:54.085 UTC: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access2, changed state to downApr 5 01:33:19.344 UTC: %CRYPTO-
[Code].....
As you can see, the physical interface (ATM0) is not being reported as changing state to down, neither is the Dialer interface.
When the router is in this state we have to SSL to the public IP address of it and manually restart the ISAKMP SA.
When the router sees the ATM interface go down and subsequently come back up, the VPN connection to the PIX also recovers.
So - in a long winded way I think I'm asking....why does the Virtual interface go down and is there anything I can do to stop it happening?

I cannot integrate Virtual MSE 7.3.101 with my Prime Infrastructure 1.2 After I setup MSE via its wizard, I make a change on WCS username and password. When I try to integrate MSE with Prime Infrastructure, Prime notify me about the mismatch username/password.
Both systems are fresh install on my UCS C220 M3.

I recently acquired a 2509 router that I plan to use as a serial device router. My question is, how do you create the virtual com ports on Windows and Linux machines to point to the TCP address:ports in the 2509 router? Is there software or drivers that do this? Or something third-party?

I have a switch from SG 500 Series the works as Layer 3 Routing Switch with the Firmeware 1.2.7.76. I have create some diferent VLAN´s and have defined one ACL for each VLAN. Now i try to do a binding from the ACl to a VLAN but i have only the option to bind the ACL to a phys. Interface or a LAG.is the a possibility to bind the ACL to a virtual interface like in other Cisco serieses and how it works ? the Backround is i have connectetd 2 Hyper-V Server where the Guests are in different VLAN´s and the server is connectetd with a 10Gb Trunk to the Switch now the switch routed the different VLAN´s and i must have some restrictions between the VLAN´s.

We want to achieve a load balancing scenario using Virtual IP on DMZ interface on a Cisco ASA 5520.
The IPs we are going to use on DMZ are 10.15.1.2 and 10.15.1.3
These IPs are going to be NATted to all inside IPs.
Lets say our outside IP is X.X.X.X
This IP points to 10.15.1.2 and 10.15.1.3 with .2 being the primary and .3 being the secondary. When I hit the outside IP, it should point me to .2 and that .2 should take me to the inside IPs.

I was just checking my router's firewall log and I noticed a couple of entries which appear somewhat suspicious, amongst all the 'normal' background radiation of (mainly) Russian and Chinese IPs: [code] The source IP for these 'attacks' is/was unused on my internal network.
My router is a Billion BiPAC 7800N running 1.06e firmware. There are a number of devices permanently connected to the internal network and a number which are connected at other times (e.g. desktops, laptops, mobile/cell phones, games consoles). Some are wired, some are wireless. Some have static IPs (none of which are listed in the above 'attacks'), some have dynamic IPs (assigned by DHCP by the router in a range not listed above). The WiFi is secured with a strong key on WPA/WPA2-PSK, AES (no WPS). Web Access Control for the router is disabled. Block WAN PING (and Block WAN (IPv6) PING) are both enabled.

We recently had a contractor deploy a 4500 catalyst switch with a WS-x45-SUP7-E. After installation and configurations, HP openview is detecting a "downed" interface on the 4500 chassis that is not in the configuration. I have attached an image with the interface circled. We assumed that it may be a configuration issue with openview, however after running diagnostics with a network analyzer, the same ip address for the down interface is still detected. Is this some sort of internal virtual interface on the SUP7?

Just replaced a WRT54GS with an E2500. It seems that anytime a connected device goes "idle" for a while, the connection breaks or severely reduces and it's nearly impossible to get the connection back without performing an action at the device in question. Let the wireless connection on my laptop go unused for some period and it reduces to 1Mbps and you can't get back on by just using the link more... you have to do a "repair".
Let more than a few minutes pass since you've printed something on the wireless printer and you MUST go to the printer to re-establish the connection by turning the antenna off and then on again.Basically the same problem with my blueray/DVD getting on the network. When I shut the screen off on my phone, the wifi dies and receives NOTHING over that link while the screen is off.
None of these behaviors existed with the WRT... just the 2500. Background/facts - current firmware, DHCP with reservations, WPA2/per, MAC filtering in use, UPnP disabled. MTU/Beacon/Frag threshold/RTS threshold set per recommendations on this site.

What are the pros and cons of configuring a Switch Virtual Interface (SVI) versus a routed physical port between layer 3 switches?For example, if I have two 4506s and have a need to run HSRP and route between them which feature is better and why?
switch_a
!
interface vlan 25
ip address 10.10.10.1 255.255.255.0
!
interface fa0/1

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.

Im currently connected to a remote acess vpn setup using the vpn client and am unable to get anywhere around my network, this normalyl works fine The only difference i can see is that the are multiple virtualaccess interfaces pointing to my public ip address, which im presuming is causing routing issues How can i clear these unsed virtual access lines and how can i make it forget them automatically after disconnects?

There is a remote server that downloads info from a server here at HQ. When the dowloads start the rxload on the S0/0/0 interface jumps to 98 percent or so; rxload 250/255. I needed to limit the bandwidth utilization between the servers, so I added the below line to the LAN interface on the remote router.By adding the command, it reduced the download utilization -which is what I wanted.
access-list 185 permit ip host 10.6.27.1 any
!
int f0/0
traffic-shape group 185 10000 8000 8000 1000
Question:How would applying this to the LAN interface cause the download utilization (Coming from s0/0/0) to decrease?

We recently upgraded our bandwidth and I have to change the ip address on our ASA 5510. I just want to make sure that I am doing it right. All I will need to do is open up the ASDM and under confiugration go to interfaces and make the needed changes to the outside interface. Then under routing I will make the gateway IP change on the outside interface.

I am setting up multiple vlan interfaces on a pair of HSRP Routers that will provide layer 3 routing for a network. I am seeing this command sporadically show up in the router config mac-address-table static 0000.0c07.acd2 vlan 210
I am not entering this command. So far, it has not shown up on the companion 3725 router. I have a 2nd vlan I have just created and the problem hasn't shown up for that vlan as yet.Using C3725-ADVSECURITYK9-M), Version 12.4(15)T7, RELEASE SOFTWARE (fc3) on the routers.

We have a Cisco 3825 router which does not work well with a DSL modem(ISP provided). I have configured the Gi0/0 port of the router to plug into this DSL modem but it does not ping to the ISP gateway. If we do a shut/no shut on the interface then it work fine for about 30 secs. Sometimes even for 1 hr. Then the packets drop and we cannot pass any traffic through this interface.Now, if the ISP connection is terminated on a computer it works fine. It works fine without dropping any packet. I have tried various options like using a straight/cross cable. I have tried to configure the interface negotiation for 100/full, 100/half, auto/auto and almost all the options. I have also tried to interconnect the devices using a L2 device like a HUB. Nothing works.

I am troubleshooting interface resets on a 3660 connected to a 3550 over Fast Ethernet. I have hard coded both sides for full duplex and 100Mbit. The 3660 is incrementing interface resetes about 4-6 times a day and the 3550 is clean. I have noticed this in other similar configurations as well.

I read that there are internal and external flash memory in 3725 router that can max up to 128mb. So adding the sizes of internal and external flash memory, will that total to 256mb?
And also is the internal flash of 3725 just the same with its external flash?

I've been trying to set up my new Cisco 1921 Router to provide internet access to my local network but with no success. I've been reading guides and looking at videos and I have to be missing something becaouse I can't access internet (ping/tracert) from my local network.
The DHCP server works fine and the clients on my local network gets ip-adresses from the router but can't ping or tracert outside the local network.

We have created more than 255 Vlans during last 5 years, and we know that eye-catching part of which are unused, I took a report from campus manager searching for Port Attributes to find out which port is assigned to a specific Vlan but as long as there are numerous ports in trunk mode connecting to Virtual servers I can not find out if unused vlans which I exclude from the report I took are really unused or not , how can I find the unused Vlans.

Desktop running Windows 7 Home Edition and connected by ethernet cable to a Netgear DG834G v2. Dell Inspiron laptop running Windows XP media edition and connected wirelessly and an iMac connected wirelessly.I did not realise until yesterday that even if I shutdown the desktop I can still connect the laptop and Mac wirelessly. I now want to stop using the present desktop and connect a new desktop with an Epson printer which my wife will use on the other side of the room. I will use the present desktop monitor on this new system. Is it easy to set this up? Also I want to remove Windows 7 from the old desktop and install it on the new desktop, will I have to contact Microsoft to do thie?
