Cisco Switching/Routing :: No Serial Connections With 2911
May 8, 2011
I have 2 2911 routers that will be connected via fiber with an ethernet Gig handoff to each router. Each router will then be connected to local networks on a second ethernet interface on the router. I have always connected routers via serial connections so this is new to me. Outside of the usual ethernet interface addressing configuration, is there anything else that would need to be configured on the 2 routers?
I have a 2911 router where I was configuring the device to allow remote desktops connections. Everything is working properly, but for some reason my ACL has disappeared.
Were bringing up a new site shortly and I'm trying to configure Serial0/0/0 which will be connected to an MPLS over 1.5m T1 line. I am basically doing a simular configuration as other sites where one of the ethernet interfaces is handed off from a fiber optic wan, but a T1 MPLS is connected to a WIC card and this provides a redundant path (though slower) in case of a fiber cut or equipment failure. This should be pretty straightforward but it appears as if I have no serial interface on this router. Card is in and everything, it is a VMIC-3-1MFT-T1/E1 in EHWIC 0.
We have a Cisco 2911 Router and have configured via BT Infinity Broadband for out going internet access etc. Are there any incoming restrictions ACL settings etc. that will stop us using for ISA VPN, Exchange connections, Intranet, Sharepoint etc. We have reserved 13 Static IP Addresses from the ISP.
I have recently purchased 2911 routers running 15.1 to replicate a system I had implemented using 2811 routers running 12.4 a few years ago. None of my applications and servers have changed, but trying to determine why my router access-list on my serial links are not behaving the same. I don't keep up with Cisco changes.
On my original system, which is a private network that distributes a lot of udp broadcast and multicast data to remote sites over 64k serial lines, I manage some of the udp broadcast data using access-lists. When I check on my 2811-based system, "show ip access-list" shows a nice distribution of filter hits showing my expected deny/permit access-list entries working as expected allowing me to filter the particular udp broadcast ports of interest on the various serial interfaces.
On my 2911 based system, with most other elements the same, the access-list is not working correctly, and I see data getting through the access control to the other side of the serial link. Using tcp dump and other tools on the remote systems my routers attach to, it looks like the access control is basically ignored... though if I "shutdown / no shutdown" the serial link between the routers, it definitely stops and restarts the flow of data, so I know data is traveling over that interface... when I run "show ip access-list" on the 2911, I see tons of hits on one deny filter, and the last "ip permit any any" filter, but other deny udp any any eq XXX port filters are simply not registering denies.. which should be triggering since I see my server sending the data, and my client systems receiving the extra data I am supposed to be filtering on the router...
Is there potentially a new feature or command set option that I am missing to correctly filter outbound data from my serial links?

I have about (12x) AS 5350 XM installed in a remote site. I would like to know their serial numbers (the one on the sticker outside the AS) I know that this SN begins with JMX and contains 11 characters. When tel netting those AS, and type the following commands : show inventory, show hardware, show version, show diag.. i can't find those serial numbers. I can find others which begins with JAE !
When I insert the TwinGig Converter in a Catalyst 4900M you get the following error message: Failed to read transceiver serial eeprom on port Te2/1, try reinserting.This error is probably because the device expects 10Gig transceivers to be connected to the device not 1Gig.I used the TwinGig 4 module and 8 SFP ports are connected. But when i type in the the "hw-module module <slot> port-group <group> select gigabitethernet" the command is not available. [code]
I have existing cisco 2811 (Version 12.4(3c)). I try to add a HWIC serial card into the router but the new HWIC is not detected. There is no new interfece shows up when i do show run. This HWIC is a new card just bought it.
While I managed to connect to each router individually, I decided it was time to connect the routers together via serial; as I don't have any serial cables and need to buy some, what serial cables I need, as well as to ask whether I have the right cards in my router(s) that will allow me to do so.
I bought 3 1841 routers, and all have a 1 port serial WAN Interface Card (WIC 1-T); one router has 2 of these, and one router has a WIC-1B-S/T .. My question is, can I connect the routers with a serial cable via WIC 1-T, or do I need a 2-T
I have two 2950 Switches and am trying to connect via my laptop. My laptop doesn't have a serial port so I am trying to connect through the ethernet port, with a straight through cable and on the end as it goes into the console port I have bought a cisco console rollover adapter.When I turn on terra term I get nothing...just a black screen and it disconnects.
I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1
Here is a show-run:
interface Multilink240 ip address 172.18.xxx.xxx 255.255.255.252 ip route-cache flow ip ospf network point-to-point service-policy output PhonesFirst ppp multilink
I am trying to find the serial number on the CLI that matches the serial number sticker on the back of a WS-C2948G-GE-TX switch that runs CatOS. I am running code cat4000-k9.8-3-2-GLX.bin. I have 4 different switches and all the stickers have a serial that starts with JPE.. and both "show version" and "show sprom 1" and "show sprom 2" gives me a completely different serial number that starts wtih JAE... All of these serial numbers I get from the CLI match with each other. The command "show sprom chassis" says "Feature not supported."
Is it possible to find the serial number that matches the sticker from the CLI on a 2948G? Why does Cisco make this so confusing?
We are having 3 internet connections coming in to one of our customer's main offices for redundancy and etc. I would like to replace the 3 routers with a one for easier support and management. One of the connections is an ADSL and the other 2 are leased lines so they terminate with an RJ45 connection.
Would something like a Cisco 2911 + HWIC ADSL card be sufficient enough or would you recommend something else?
We are about to install a cisco 2911 router to replace a linux based router.
The Cisco will have 5 gig ports, 4 ports connected to DSL modems each modem connected to a different ISP, and the last port connected to a Cisco LAN switch.
802.1q will be used on the internal router port to split the LAN segments up into VLAN's as the building contains lots of different businesses.
Each customer in the building has there own servers and set of public IP addresses assigned e.g
Customer A - ISP 1 uses 81.34.65.78 NAT'd to 10.0.0.1 Vlan 5 port 25 (SMTP) Customer B - ISP 2 uses 217.23.67.87 NAT'd to 192.168.1.1 Vlan 6 port 25 (SMTP)
and so on
The outbound traffic also needs to go out of the correct DSL line which ever has been assigned to that customer.
Am i right in thinking the only way to do this will be to use "Route Maps" ??
(IP addresses above are made up, or at least not ours)
I am using Cisco 2911 & IOS version is 15.1. My problem is that after some days (e.g. 15-20 days), the routing table suddenly stops updating & then I have to enter the default route again to make it up. I am using Track 1 to track default route here. After primary link goes down, the Track is also going down but after coming the primary link up, the track is not coming up. So, I have to add the default route again to make it up.
I have been looking for the command to view all concurrent active connections or sessions on our Cisco 2911. I want to see what the total connections or sessions are at peak times throughout the day.
after installation of demo versions of 2900-SEC-TEMP & 2911-2921-SSLVPN-TEMP & rebooting the 2911 router I do not have access SSL commands.Show license indicates that 2900-SEC-TEMP & 2911-2921-SSL-TEMP licenses are active but NOT IN USE.
I have a 2911 router. One interface is configured external (WAN) and two interfaces are configured on separate internal private subnets. What is the configuration to allow all traffic in both directions between the two internal subnets?
I have installed a cisco 2911 router and the cisco usb console drivers on my pc, win 7 64 bit.however when I use putty and open the com port assigned it just goes blank, I am using the usb port on my laptop to connect and using the cisco usb console cable provided
I've got two routers, Cisco 2911's with 15.1(4)M1 on one and 15.0(1)M5 on another.
I'm trying to set up ip sla for vrrp tracking but the commands seem gimped? I don't even have an option for ip sla <operation number>. All I've got is ip sla responder/server/key-chain.
we are in the planning phase for a network upgrade. We have two C2960 Switches connected via one (L2) Etherchannel (4x1 Gbit/s) which works very well. In the next phase we would like to upgrade our router to an 2911 series which has 3 gb interfaces. and indeed we would like to create an etherchannel as well. our plan is to use 2 of the 2911 to connect to the first 2960 switch and the one left to the other 2960. i think we will achieve some redundancy with this config.
connected DSL directly to 2900 series router , but as DSL public IP is not static (dynamic) its difficult to access Router when out of home, any other means to access router without static IP
we have bought 2911 router recently has to set up VOIP line seperately for the network we have two two broadband service provider:
1. how can i use 1 line as an active and other line as a failover(when 1 line is down other line should automatically bear the traffic).clear config will be useful. NATTING using MAtch address objects( roughly )
broadband service provider 1: 97.89.X.X 255.255.252.0 broadband service provider 2: 10.0.x.x 255.255.240.0
2. there are only 20 users to set up a voip line now. here we have telecom provider where they should route the traffic to make any international calls( say telecom public ip 200.200.109.110)from lan - wan everything is allowed from wan -lan we have to allow only telcom provider IP(200.200.109.110)
