Cisco :: Cannot Increase MTU To Support Extra Four Bytes Of VLAN Tag
Oct 22, 2012
We have an EHWIC for a 2900 router. Apparently, this card supports QinQ.. However, there is no usual MTU command. Therefore we cannot increase the MTU to support the extra four-bytes of VLAN tag. We have tried 15.2 and 15.1 code. May be the command is different. I'm about to go and do some digging elsewhere.The card is EHWIC-4ESG.
How do I submit an RFE (Request For Enhancement) to the Cisco SBR team to encourage them to implement the missing support for VLAN to VLAN firewall rules that was available in the RVS4000 (See [URL]) and that was supposedly added to a beta release of the RV220W firmware (See [URL])?
Coincidentally when i tried to configure router 877 as an adsl router i found that a vlan configuration is included. my question is what is the benefit of using vlans in router ??? i studied that we use it in switches for the purpose of network enhancment from broadcasts and netwrok segmentation. why we use vlans in routers ?
I have a 857w and a 857 router but there doesnt seem to be any HSRP and VLAn support on either router. I have ADVsevcurity on the routers do Ineed a different IOS or is it just not supported.
Critical voice vlan feature, used to place a newly authenticating phone when radius server is dead into appropriate voice vlan, seems to be a new feature and I find the documentation to be incomplete. Do the following switches support this feature in any IoS versions? WS-C4510R, 4506, 3560, 3550,2960s.
We bough an Cisco 2911 router, and as i see the "ip sla monitor" command is not supported. Which license/IOS upgrade should i buy the fullfill this. And i cant add a trunkport to the iunterface even cant add a vlan to interface. How do i a trunkport on the cisco 2911 router. ANd how can i do a vlan on a interface on the router.
We're going to be switching some of our gear from Foundry to Cisco, and were looking at the WS-C2960S-48TS-L. We currently have 3 different VLAN's, and I wanted to have 1 uplink back to our firewall (ASA 5550) and then let the firewall do the routing between the subnets. I realize that 1 link will carry the traffic twice then, but is that possibly with those switches to have all three vlans assigned to one port and then just let the firewall do the routing between the vlans or would I need to have 3 uplink ports back to the 5550?
I would like to know can we configure vlans with cisco 1721 Modular Router? Is it Possible to configure lan environment with the vlans configured in 1721 router without a managed switch?
I have a problem with my vpn between two ASAs, I review the running config of two devices, but I couldnt see anything out of normal.As you can see in the image the VPN is up, but in the ASA 5510 I don't have Bytes Rx (ZERO), I tried to config again two ASAs but I have the same trouble.
For the last 3 weeks or so (right around the time I upgraded to IE8), my computer has been receiving a ridiculous number of bytes compared to what it sends.Within 5-10 minutes of logging on (I still use dialup), a check on the status shows around 100,000 bytes sent and over 2,000,000 received.I've been online for around 40 minutes, and it currently shows 650,000 sent (23% compression rate) and over 5,000,000 received (4% compression rate).Of course, the browser starts lagging and freezing after a while, which I assume is from the large number of bytes being received.
At the same time, there's a noticeable lag when I try to run programs, even when offline. For example,I click on my ISP connection and nothing happens for 5-6 seconds, then the dialog box appears. This is something that's never happened before. I'm running XP Home and no one else has access to my computer.I'm using the standard Windows firewall.I've run my AV and spyware programs multiple times (nothing found), cleaned my temporary files and cookies, even adjusted the FIFO buffers (the last thing I tried was turning the buffers off). I've been running Disk Cleanup everyday (which lags and runs slower than ever before), but it doesn't solve anything.I don't know how to adjust the compression rate for bytes received to see if that works.
I have a RV042 with a DSL (static IP) and a cable connection (Dynamic). How do I get the extra bandwidth from the cable and still keep the static IP of the DSL. When I have the router set on WAN1 (DSL), I get buffering. When I set the router on WAN2, I lose the static IP and therefore, the stream. When I have the router set on Load Balance, it switches the IP back and forth between the static DSL and the Dynamic cable.
I work most of the time at home so my work installed a WatchGuard Firebox SOHO 6 router at my place so they could make a secure VPN connection between my laptop and my work.All the other computers and gaming consoles at my home are also connected to this router. But they aren't connected with the VPN. Click here for a scheme of my current configuration.Now my question is: Can I place an extra wireless router (eg. D-Link DIR-855) between my cable modem and the watchguard router without blocking the VPN connection?I want to use the watchguard for my work laptop only and the new router for all the other computers and laptops.Click here for a scheme of the configuration that I want.
When i check the status of my Internet Connection I notice that the sent and received bytes keeps increasing. I'm sure there are no downloads taking place that I'm aware of. No torrent clients, no antivirus nothing. I checked my PC for malware but that didn't work. As a result of this, i keep getting high pings in online games and can't even watch videos in youtube anymore. like, some software to monitor all the programs that use the itnernet connection without my knowledge or something??My primary concern is gaming (Call of Duty 4) so I wouldn't mind this idle downloading (whatever it is) as long as the major chunk of my internet connection is directed towards Cod4!
This has been happening of late. When i check the status of my Internet Connection I notice that the sent bytes will be more than 200 and received bytes will be low as 2 to 4
When i look at the network wirless connection status something is constantly sending and receiving Bytes and lots of them.the modem gets warm from all of the activity.
I used speed test and got 50 mega bits per second. I tried re downloading tf2 and i was getting 80 kilo bytes, and I am using windows 7. Doesn't 8 mega bits equal 1 mega byte?
This has been happening of late. When i check the status of my connection, i notice that the "sent" and "received" bytes keeps on increasing when i'm idle. I'm pretty much sure there's no downloading of any sort in progress that I'm aware of. As a result of this, I can't watch videos in Youtube or play online games due to high ping.
I am blocked with the below doubt for my issue resolution. When a ethernet frame for eg:ARP Packet of minimum length (64 bytes) is received at the end station, will the L2 layer remove both FCS and extra padding bytes(18 padding bytes for ARP)? Or removal of the padding bytes is dependent on the implementation?
i want to use a wireless router to hook-up my HD-TV to use it as a monitor. at the same time that my son can play his PS3.Do i need an extra keyboard to use on my HD-TV?
I have DSL from verizon and the modem is also a router with wireless n capability. i want to add my old belkin router to the system via a hardline to the verizon one. i need to know if this will cause a conflict between the 2 routers.
Currently i have one main router in my house connected to the phone line. what i want to do is add another standalone router which will wireless connect to my main one.i want to connect my computer to the router wired then that router connects to the main router wirelessly.what is this method called ive seen things like wireless repeaters and wireless bridge.
We have a new router (D Link) at offices which is fixed with LAN wall points on different places , we want to use it .I connected computers to the LAN points with regular lan cables , it gives me the alert (connected) but no bytes received .I tried to ipconfig an here's what i got :Windows IP ConfigurationEthernet adapter Local Area Connection 2[CODE]
I am using Win 7 Pro x32. When I use RDP to connect to another computer, I noticed that on the remote computer (sometimes) as well as on my local machine (always), it creates a "Z:" drive. It isn't like a mapped network drive though, it shows under Hard Disk Drives. The free space is the same as the C: drive. When you open it, it is the %TEMP% folder on my machine. Going to the run command and typing %TEMP% will show you the same contents as the Z: drive. When I close the RD Connection, the Z drive goes away. I have no clue what is causing this and I did a little searching and couldn't find anything that resembled anything close to this online. I saw the same thing happen on a Win XP machine earlier as well.
We have a Cisco 881 router, which is crashing. We have seen that the ARP cache fills up so much it causes things to crash, our phones go down.. We dont know why this however IP CEF seems to be doing it, when we disable it goes away however disabling IP CEF causes our L2TP tunnel to become inoperable also. So why does IP CEF cause thousands of AR entries and how can we limit that!? Below is the error, sample of the ARP cache and our config. You will notice we also have a /31 given to us on WAN interface, this was given to us by our service provider. This is really strange I cant find other examples on internet.
The error:
Nov 1 04:21:57.474: %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from 0x81F083F4, alignment 16 Pool: Processor Free: 55176 Cause: Not enough free memory Alternate Pool: I/O Free: 2352 Cause: Not enough free memory
I need to count the bytes for some interesting traffic crossing the firewall in ASA 5500. Packet Capture is so far as I need, cause I only need the number of bytes during a long time for about 3 months (source host - destination host)
capture capin type raw-data access-list cap buffer 33554432 interface inside circular-buffer [Capturing - 33553570 bytes]
I need to get only the exactly amount of "33553570 bytes" The pcap file is not needed
url...For the New Firewalls i.e. 5512X , 5515X etc there seems to be integrated IPS and we don't need to order any extra license or part number to get the IPS features .
But for the 5585X It says 2Gbps for SSP10 engine but I have seen in the Dynamic Configuration Tool that SSP10 and IPS-SSP10 are different things . Which means that I will have to order 2 service engines SSP10 and IPS SSP10 to get the IPS features and if I only order SSP10 with that Chasis I will only get firewalling ?
i was looking at my network settings today on my pc and noticed a router (linksys wrt160nv2) that wasn't mine. i can right click on it and see its mac address but when i double click it asks me for a pin number. the device shows up with both a wired and wireless connection. i'm using windows 7 64-bit.
