Putting in a 1Gbps private Ethernet link between 2 sites. Currently have 2 2811's at each location, don't think that will cut it.
I was going to get 2 2911's, but looking at the docs it looks like they can only do 180mbps of throughput? Am I way out of my league here?
I have a working configuration with a 2811 router at my remote site in which I take the T1 (point-to-point PRI) into port 0/0/0 on the dual-port vwic2-mft-t1/e1 card. Then I plug my PBX into the 0/0/1 port. I channelize the T1 so 1/2 of the channels are used for data (13-24) and channels 1-8 are passed through the vwic2 to the PBX. I'm using the connect tdm t1 0/0/0 0 t1 0/0/1 0 command to pass the voice calls through to the PBX.
I tried to upgrade the router to a 2911 with the same card and the same configuration copied and pasted over and as soon as I put the connect tdm t1 0/0/0 0 t1 0/0/1 0 statement in, I drop the data side of the T1 and lose my connection to the WAN. If I take the command back out, the WAN still doesn't come back up until I reboot the router.
Has the syntax changed? I have a case open with TAC but so far no luck, as they can't seem to figure out which group should take this case, voice or data..
We have CISCO2811 model with VWIC2-2MFT-T1/E1 module working good over the E1 line. Since it's getting hard to find new model of CISCO2811 we decided to connect new branches with CISCO2911/K9 model (according to migration doc)
My question is can we use 2811's old config file with the 2911 model directly?
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'm looking to use a Cisco 3945E to terminate a 1Gbps Ethernet internet connection and I want to know the realistic throughput that I can expect. The router will only be configured with BGP with partial routes. No firewall or QoS will be configured.

View 4 Replies View RelatedI have a PC that I built with an Asus P8Z68-V PRO motherboard and I just bought the Negear WNDR4500 router. I am unable to connect to the PC to the router at a link speed of 1Gbps. when I go into the properties of the nic card and set it to 1Gbps, it doesn't connect and says the network cable is disconnected. If I choose auto-negotiation, it will only connect at 100Mbps. I have other devices that can connect to the router at 1Gbps just fine. I have tried the latest nic drivers from Asus's site, I tried installing windows 7 64bit from scratch, I reset the router, upgraded the firmware. all my cables are cat6 or better and I even tried removing all other devices from my router. I just can't get it to connect at 1Gbps.

I tried switching to a newer and better motherboard (still with gigabit LAN)I have updated drivers.I have checked cables (which are all cat 6 cables and work just fine with other computers in gigabit LAN mode)I've checked and switched ports on the switch and the switch itself...no change. They work just fine with other non-W2008 machines, they get gigabit LAN
I am completely stomped as to what I can do to fix this. It runs just fine in 100 Mbit mode, but can't in any way get it in gigabit mode.I am completely stomped as to why it refuses...is this a limitation of Windows 2008 or something or is there a fix to this?
i've connected a laptop with "Realtek RTL8168C(P)/8111C(P) PCI-E Gigabit Ethernet NIC" to a onboard NIC of Asus M4A89TD Pro wich is "Realtek 8111E Gigabit LAN Controller", which both support 1gbps but they will auto-negotiate at 100mbps.
View 5 Replies View RelatedWe are testing a new 1Gbps WAN circuit between 2 sites. We have cisco 3750 and 4507 on each end. Every time we run extended ping sweep ranging from 36 to 18024 bytes the packets are being dropped randomly once the size goes above 1500 bytes. Our ISP claims Demark to Demark test are clean and they don't want to acknowledge the problem, they blame our switches. To prove the problem is not on our end we've put different switches at each end, still facing the same issue. Ping success rate is around 98 to 99 percent.

Recently they bought a new Cisco 2911 router and told me that they want it connected to an outside WAN connection that they hadn't used in a while so they could create a little network on the side. They want to just plug the server into the router and go. Unfortunately, I am sort of clueless about how to set up the config for it.
There are 3 GE ports, with the line from the outside coming in on GE0/0. I've already activated the interface and it is up, but that's where I get stuck.
I am connected to my internet with
WAN Interface
gig0/0 interface
ip add 62.x.x.x 255.255.255.252
duplex full
speed auto
LAN interface
gig0/1
ip add 10.x.x.x 255.255.255.0
duplex full
speed 100 ( i am keeping the speed 100 because it is connected in switch port f0/48,made the switch port as speed 100)
but after some time my connection to the internet goes off and i just shut and no shut the WAN interface and it comes back.
i have problem with a router 2900 with a card switch 16 ports (sm-es2-16p) that does not doing the intervlan routing. i have attached 2 show tech one of the router and one of the card switch 16 ports (sm-es2-16p). I connected physically the switch card to a router interface and it seem to be working because i can do a ping from my pc ( in user vlan 26) to my gateway on the router (172.20.26.1) but i can not do ping to the others vlan like (172.10.26.1) or others. .. i want to know what is happening and if it there is a way to do the trunk conectivity between the switch card and the router internally without a phyisical connection.

Suppose a broadcasted IP packet reaches one of the integrated RJ-45 ports on a 2911 ISR G2, will it be possible to configure the router so that the other integrated RJ-45 ports, ESM/EHWIC modules installed on the router, as well as the MGF also recieve the packet? Technically, the router should act similar to a switch with the SRE behaving similar to a seperate machine connected via the MGF and other external machine connected to the ports of the router to recieve the broadcasted packet.
Also, if SNMP traps were generated from the router,Will it be possible to send the traps from the router via the MGF to the SRE installed on the router?
We have configured new 2911 router with HWIC-2T with it.However we are seeing serial interfaces up, but can hardly ping other end. Again we are seeing a lot of CRC errors on serial interface.
But if we connected same cable, with other old router 2811, it works fine. Confiuration is same on both the routers. [code]
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 have an old Cisco 2600 series router, running a single T-1 line, AT&T is the carrier. Very standard stuff.
The T-1 works perfectly on the old router. Cisco 2600 with a WIC-1DSU-T1 card. We have a brand new 2911 router with a VWIC3-1MFT-T1/E1 card in it. The circuit runs 100% clean and trouble free on the old router. When I plug it into the new router, it shows up/up but has a massive number of errors on the line, and the circuit is not usable. There are no timing slips or anything like that.
I have another site using the same router and card with the same configuration on that T-1 and it works perfectly. Zero errors. This site (in a different city) is totally slammed with errors. We already replaced the T-1 card and still have the exact same issue.
I've actually been doing this a long time, and I've tried all of the usual things, adjusting line build out, changing clock source, checking and re-checking configs. Nothing seems to reduce the error rate.
I personally think it has something to do with the Smartjack. Like maybe their LBO is too high or too low, and the old router card was more/less sensitive than the new one?
This is a layer 1 issue and is not defective hardware or defective configuration. I am looking for T-1 insights or bugs/issues.

I had purchased a HWIC-8A in an effort to provide terminal server capabilities into multiple routers. I had found a document that I thought would take me through the configuration but it doesn't appear that the command syntax is the same on the 2911's as it is in the document. Does any know how I would need to get this configured on the 2911 router?
