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.

Cisco Switching/Routing :: 2960 Support Multiple Vlan Per Port?

May 21, 2012

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?

Receiving Way Too Many Bytes?

Feb 12, 2011

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.

Cisco WAN :: RV042 - How To Get Extra Bandwidth

Sep 1, 2011

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.

Adding An Extra Router Between VPN?

Feb 6, 2011

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.

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.

Sent And Received Bytes Increasing When Idle?

Jan 20, 2011

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!

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?

Extra Z Drive To Temp Folder During RDP Connection?

Jan 12, 2011

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.

Cisco WAN :: 881 / Memory Allocation Of 65536 Bytes Failed From 0x81F083F4 / Alignment 16

Oct 31, 2011

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

Cisco Firewall :: 5512X Any Extra License Or Part Number To Get IPS Features

Apr 30, 2012

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  ?
