Cisco WAN :: 2811 / HWIC-2SHDSL - How To Configure Two Independent SHDLS Connections Through One
Mar 16, 2010
I've been collecting information on principles of SHDSL connection. I have found plenty of examples on how to configure only one SHDSL link. Very soon I'm going to the site to install two independent SHDSL links in Cisco 2811 which has one Cisco HWIC-2SHDSL module, so I can route one type of traffic through one connection and another type of traffic through another. Both SHDLS links have static IP addresses and probably different VPI/VCI values. how to install two SHDSL links into one HWIC-2SHDSL module, set one value for VPI/VCI on one link and another value for VPI/VCI on another link, also set one IP address on one link and another IP adddress on another link?
I'm looking for a HWIC card that will support SC fiber connections for a 2811. I know of the HWIC-1GE-SFP but this one only support the LC connections.
I have a scenario where multiple branches are connected to Head Office via DSL links. The branches are located in differenct exchanges, everyone once in a while ALL branches go down at the exact same time except 3 branches and those 3 branches don't have ATM interface on the router, rather they have external DSL modem, all other branches that face the disconnection (for couple of minutes) have either HWIC-1ADSL-M or HWIC-2SHDSL and the DSL line is directly plugged into the card. [code]
I tried so many solutions like adding "operating-mode auto" command under the subinterface, IOS upgrade, changed dynamic routing protocol from EIGRP to OSPF... Nothing worked, on the logs of the router it just shows "EIGRP neighbor down", at the time of the problem I can't ping any of the affected branches on their WAN ATM interface although it stays physically "up up".Could the problem be a missing command that I need to add under the subinterface? Something maybe related to clocking or timeout or..?Note that hte problem occurs randomly, every few days, sometimes every 10 days, and all branches with ATM interface go down at the exact same time.
I'm having problems to ping through interface atm 0/0/0 which is releated to a card HWIC-2SHDSL . The router I have is a 1941. I dont know what to do. [code]
I am trying to configure a shdsl port on a 2911 router for CO mode of operation.The dsl-group auto command does not seem to change the port to operate in CO mode and the link will not come up to a remote router that has a card installed operating in CPE mode.The configuration I have applied for the shdsl controller is.
controller SHDSL 0/1/0 dsl-group auto ! !
Do I need to use a HWIC-4SHDSL card for the CO mode operation?
I am trying to configure a newly installed HWIC-4ESW on a 2811 router to bridge to the FE 0/0 interface. Currently, I have a cheap switch connected to FE 0/0 which in turn connects to all the phones, however now I just want to connect all the phones to the HWIC and have it internally bridge to FE0/0 for the connectivity to CME, etc.
I have a WS-C3750G-24T-S layer 3 switch and I need to configure independent routes for a specific network, I'm trying to use VRF but it is not working for me. I tried using route-map but it seems the switch doesn't support that, so I'm stuck with VRF, but I think I'm not doing it right. The topology is as follows:
I have a network directly connected to a vlan and I need to forward all the traffic I get on this VLAN using a tunnel to a router. I think the problem is that in order to use the tunnel I need to utilize another VLAN which isn't part of that VRF. I attach the configuration I'm using to better understand what I'm trying to do:
layer-3 switch:
ip vrf TEST rd 1:1 interface Tunnel1 ip vrf forwarding TEST ip address 172.17.0.1 255.255.255.252 tunnel source 10.245.0.9 tunnel destination 10.250.4.31
[Code]....
And this is how my routing table looks on this router:
172.17.0.0/30 is subnetted, 1 subnets C 172.17.0.0 is directly connected, Tunnel4 C 10.250.4.0/24 is directly connected, Vlan404 S 10.245.0.8/29 [1/0] via 10.250.4.1 S* 0.0.0.0/0 [1/0] via 10.1.60.15
I have a Cisco 2811 router with c2800nm-adventerprisek9_sna-mz.124-2.T6.bin as IOS and i wsh to install this HWIC 4port to increase available ports on my router. Wish to know if this is going to work,that is, if i installed it the IOS available will recognise this card
I would like to ask if a cisco 2811 running on an ios c2800nm-adventerprisek9-mz.124-25a.bin should be able to make an HWIC-1FE card work? I am also not detecting the card on any show commands. Plus i am seeing that all the LEDs (FDX/COL,100 and LINK/ACT) are lit steadily even though there is no cable attached to it, is it safe to say that the card could be defective?
i am currently trying to configure a four port ISDN BRI interface on a Cisco 2811 router.Upon upgrading to a later version of IOS, c2800nm-advipservicesk9-mz.124-25d.bin, access to the HWIC-4B-S/T module is lost, the router no longer detects it. In fact iI can only get the router to detect the module using the original IOS version c2800nm-advipservicesk9-mz.124-20.YA3.bin.
Is there some special feature needed in the IOS code to support these modules, if so what would be a suitable version/train to upgrade to?I have tried using the Cisco Software advisor tool but it generates an error when searching on a hardware configuration containing this module type.
The reason for upgrading the code is we have a potential bug with the current version which appears to be preventing the BRI interface syncing up with the providers switch (switch type correctly defined and provider confirms isdn line has been provisioned correctly).
The debug error seen is:
GMT: ISDN BR0/0/0 SERROR: L2_Go: at bailout DLCB is NULL L2: sapi 63 tei 127 ces 0 ev 0x650
My main question though is why the module is not being detected after a code upgrade and if there is a specific code version/train needed to support this module in a 2811?
I am adding another ISP (and plan to use BGP). I am looking at having two 2811's with one connected to each ISP, or a single 2811 (with an additional HWIC) connected to both ISPs. I am not sure if there is a best practices or an ideal configuration for this.
Currently I have:
ASA5510 ---> 2811 ---> ISP_A
Should I purchase another 2811 for ISP_B and connect it to an available port on the ASA? Or should I just purchase a HWIC-1FE and add ISP_B to the existing router?
I see some advantages to both, but not sure the best way to go. Of course, I could be looking at this wrong and if I plan on buying another router then maybe I should use HSRP and both routers should connect to both ISPs.
I have a 2811 router runnning IOS 12.4(21) and have added an HWIC 1FE card to slot 2. But the card doesnot show up in the router and all the three lights on the HWIC card is steady green. I have gone through some cisco documentation and found that i have to upgrade the IOS.
I have few questions before doing the upgrade.
1. Which IOS version should I upgrade to?
2. Will this erase my exisitng running configuration ? I have VPN services, PPPoATM, PBR etc.. all running on this router at present.
3. Presently i have a 128 MB CF card on the router. Will this be enough or do i need to upgrade this card also? Can i choose an IOS which will fit into this card otherwise while keeping all existng features?
4. I want to use the HWIC card for the ISP's internet service through PPPoE. Will this be possible with the upgraded IOS ?
I have a module of HWIC-4ESW installed into Cisco 2811 router where 3 WAN link is terminited. Suddently WAN links stopped working from last night. I have performed shutdown and no shutdown in the interface but still the the WAN link was not working. After performing a reboot the WAN link started working. No error logs were generated while the WAN link was down.
I currently have a Cisco 2621 powering a network at our co-location facility... It's a simple setup and is working well. The colo provides a redundant HSRP uplink, so I have their two uplinks going into a Dell switch. From that Dell switch I have a uplink into FastEthernet0/0 on the 2621, configured with my routing network, and then FastEthernet0/1 gets an address from my block of routable IP. FastEthernet0/1 then plugs into another Dell switch where I have all my servers connected. The servers get public routable IP addresses and use the address on FastEthernet0/1 as their default gateway.
It's time to upgrade off the 2621, so I aquired a Cisco 2811 which has two FE interfaces, as well as a modular HWIC-4ESW switch. My question is, can I get rid of the Dell Switch A in the setup above and just use the internal switch on the 2811 to accomplish the same thing? And I if I did this, would my two uplinks from the colo plug into ports 1 and 2 of that HWIC, and then port 3 would physically connect into FE 0/0? Or can I logically do that via configuration in the Cisco? I'm not sure how all this works and haven't received the new router yet, so I thought I'd get a head start and reach out to the experts.
My second question is unrelated, but each port on the HWIC switch cannot be configured as a network interface right? I'm pretty sure they can't as they aren't considered network interfaces but just thought I'd ask.
I tried to configure a 2920 with a WIC=HWIC-1CE1T1-PRI. In the serial 0/0/0:23 I set the isdn switch type to primary-ni2c. When I then exit configure mode and show interface se0/0/0:23 the switch type has been changed to primary-ni. Is this normal?
we bought the Cisco 1921 ISR with the HWIC-1GE-SFP to get a router that would be able to connect via fiber to our switches. I called Cisco and their reps recommended this router/HWIC pair to me.
I have got the basic configuration out of the way and I have discovered my router with CCP, now I would like to know how I can configure this HWIC. I have the SFP(GLC-SX-MM= ) installed correctly and it is connected to our test switch via an LC/LC cable, but when I do 'show ip interface" all ports are down except the one my workstation connects directly to the router with (gigabit0/1).
Is there a way to configure a 28xx series router with a HWIC-AP card as a wireless client instead of a wireless access point? There isn't a network drop in the location that I need to place a router, but there is an active Access Point that reaches the area.
I have a client machine that requiers a DSL connection
my office already has a leased line to the building so don't want to pay for a DSL and BT phone line.
Can i configure my 2811 to act as a DSL server so that I can plug the clients ADSL modem into my router and let it think that it has a valid DSL connection.
Then the 2811 can provide internet over my leased line.
configured 2 EzVPN groups using a 2811 router, i am trying to do this but is not working i have another VPN working thru EzVPN but if i try to configure another group for another EzVPN client is not working and the problem is that the debug crypto isakmp say that Apr 3 08:45:25.802: ISAKMP:(1309): phase 2 SA policy not acceptable!
How is that possible? in my understand the EzVPN server will inject the the IKE (phase 1) and IPSec (Phase 2) parameters for the client and that's they dont need to negotiate nothing, is important to say that the EzVPN client is an ASA5505 with onlu DES encryption enabled, 3DES and AES are not available due to licensing reasons.
Facing a unique problem in my cisco Router (2811) .. Router is well configured but suddenly it stops working , when logged in using console the configuration register is observed to be 0x2142.
How does it automatically changes register value during operation?
My network routing (both routers are consumer-grade NETGEAR WNDR3700) is like this:
Modem ==> Router 1 ==> Router 2 WAN Port
I have Router 1 set to DHCP the entire home network. I want Router 2 to section off a web server from the home network in case it gets compromised, but I want computers on the home network to be able to administer the web server.
As it stands, the web server can access PCs on Router 1, and not vice-versa. In effect, I want this to be reversed. Can this be done without changing the physical configuration?
All right, I bit the bullet and switched the router chain so Router 2 comes before Router 1. Set up was so easy and though it's not perfect, it's all ready!
I'm am wanting to know how to configure Easy VPN server with downloadable ACLs on a cisco router 2811.
Indeed, I would like to set up a remote access vpn that uses radius for authentication of VPN clients. The radius server is connected to an Active Directory server that contains the log in / password. I would like to on the basis of the user who connects to the VPN, the ACL that define the services or servers to which this user can access is automatically applied on the router and define the rights of the users.
Currently 2811 series router is configured for site to site VPN, CAN I configure USER VPN on the same box. We want Users to connect to VPN Server using Cisco VPN Client. best authentication method for USER VPN
configuring policy based route for my cisco router?Basically, I have a 2811 cisco router with 2 ADSL ports. 1 port is for iiNet line and another port is for Telstra line.I want to configure a policy based route on the router so that:Any traffic coming from 1 internal IP (i.e. 172.16.x.1) will go through iinet line (i.e. Dialer 0) interface.Any traffic from rest of the office will go through the Telstra line (i.e. Dialer 1) interface. Is there any easy way to configure this policy based route?
