I need to use very long console connection it over 56 feet (17m) (I used Cat6 wire with connection on oth ends as console wire 12345678-87654321) According to the below table
Data rate (bps)Distance (m) 2400
60
4800
30
[Code]....
I've configured all my devices in the lab to use 115200 baud rate, so I can speed things up a little at the console. For whatever reason, I can't get my 3550 to save the 115500 baud rate. I power on the switch, hold the mode button, at the switch: prompt I type 'set BAUD 115200' followed by a reset. I power the cycle the switch once more, yet it still holds at 9600. I did the same process on my 3560's and it worked like a charm.
View 3 Replies View RelatedHaving trouble resetting the baud rate to 9600 on a 3750-E. Basically the device cannot be set to anything other than 115200 baud rate. I have changed this via startup-config (which lost connection) reconnected and saved config but after reload was back to 115200. Tried via bootloader to 'set 9600' but the termial program paused for a bit then the switch prompt returned. Tried the same to 'unset baud' but the same thing as above happened. I have erased and reloaded flash etc

View 8 Replies View RelatedI have a 2921 router with 1 etherswitch module installed. I haven't done it before and was trying to change the baud rate to 115200 for installing an IOS on the etherswitch module which had been deleted. I ended up "unsetting" the baud rate on the etherswitch and rebooted. Now, when I try to session into the etherswitch, its opens the connection but I can no longer see any text on the screen. Im using Teraterm. I've tried different baud rate settings for my serial port in TeraTerm but still cant see any text on the screen. I dont know of any commands from the router prompt. Any suggestions to fix this? If can start seeing the text, then I can probably configure and set up the etherswitch module.
View 1 Replies View Relatedit seems that i made a mistake when typing the BAUD rate of a 2960-Switch in rommon.I can't start the switch now, because there is no image on it (because I deleted it before) and the baud-rate has wrong settings. When connecting via console cable i can't see anything (except some strange hieroglyphics) when starting. I tried all the speeds in teraterm... without success.what can i do, to recover the switch back?

We verified our serial connection works - 9600; 8bits; 0 and none works on other devices. When we connect (via Console) we get a blank screen with a blinking cursor. We can't get to it from GUI/Web as well. Tried depressing the reset button and we see the LED's flash from yellow to green, but still no access. Our web search has not produced any useful ideas.
View 2 Replies View RelatedI'm trying to limit one of my inside hosts, since it's been a little of a hog. I have 3Mb available from my ISP via 2x T1. I'm testing this on a computer in a lab:
PC 10.10.10.10------Cisco2960-------- 10.10.10.1 Inside - ASA - Outside 208.66.x.1------------------------208.66.x.2-Cisco 2811-2xT1
Here's what I've tried so far, please see text in red:
***global (outside) 1 208.66.x.115
***nat (inside) 0 access-list No-Nat
***nat (inside) 1 0.0.0.0 0.0.0.0

It didn't work... I was able to max the bandwidth again. I also tried to apply service-policy to inside int, which didn't make a difference.
i have configured some 1142n's, everything works in terms of .n but the reported client connection on the AP does match the published MCS definitions.eg so what does "Current Rate (Mb/sec) m6-4" actually mean in terms of MCS connection

CONSOLE:
I've tried connecting from the PC's serial port to the units console port using Cisco's blue cable with no avail. All I get is a cursor but no response. I've tried using 9600,8,none,1,none as settings and I can sucessfully console a Cisco 1700 router with those same settings in Putty no problem, but it doesn't work with this Pix. I've also tried using other possible common speeds like 1200,1400,4800,19200, 38400, 57600 and 115200 in case the firewall was set to use those and that didn't work either.

Worried about denial-of-service attacks. They have 11 vm's that share a connection and want to set it up so that there is a maximum amount of traffic allowed to hit each vm, so if there is a DDoS attack it will only affect that one VM instead of all the VM's on the same connection.
What is the best way to go about this from the ASA? This is behind a 5515 with asa code version 8.6. Is there a way to rate-limit by ip address?
I'm trying to access our ASA 5512-X via the Management port, but the address https://192.168.1.1/admin can't be displayed.
View 35 Replies View RelatedOur main ASA5510 is set up to failover to a second 5510, and is using the management port for that purpose. All of the other LAN ports are in use.
Currently we can manage the ASA using ASDM5.2 from and device on the LAN.
We are now going through PCI Compliance, and one of the vunerability scans has picked up the fact that the firewall appears to accept connections on SSL v2. However, if I try to set SSL to use v3 or TLS v1 only (as we don't use webVPN), I get a message that I will no longer be able to use ASDM to manage the firewall as changing to SSL v3 will 'prevent ASDM from establishing a secure connection with the ASA'
So does this mean that the ASA does use / accept SSL v2? The help files say that it will accept 'hellos' in v2 but will then try to negotiate to SSLv3 or TLS v1. It doesn't give more details about what happens next, but I would have assumed that if it can't negotiate to one of the later protocols it will drop the connection - is this correct? If that's the case I may be able to get PCI to accept it.
However, if this is not acceptiable and I have to switch to SSL v3, what options do I now have of administering the ASA through a GUI?
I have two 3560s that i would like to upgrade. But first i would like to make -absolutely- sure i dont wind up in a situation where i have to roll back over a console connection.to the day i still cant understand why oh why someone removed (or chose not to implement it everywhere) tftpdnld from rommon ;)
View 8 Replies View RelatedI'm trying to determine whether Cisco has any equivalent (in any platform) to some of the existing firewall rules within our iptables infrastructure. [code] What this does, is allow port forwards on port 3389/rdp. However, if a single IP opens too many connections within a timeframe, it starts dropping new ones.This is a critical requirements for certain security scenarios, such as preventing RDP brute forcing. A similar principle can be applied to 22/ssh.I've had a look around, rate limiting searches generally land me on QoS based discussions. I've seen people ask similar questions and get referred to CBAC. Whilst I can see similarly worded functions there such as limiting "half open" connections, I don't see anything there that limits the actual number of connection attempts you can make.

View 1 Replies View Related We have an ASA 5525 running version 8.6(1)2 and a 10 MG pipe. I have execs that want to limit bandwidth on users for stuff like youtube, stream media, and downloads. I found the article on ‘Bandwidth Management(Rate Limit) Using QoS Policies’ so it appears our firewall can do what we want. I’m not a cisco person. My knowledge is limited when it comes to configuration – that’s why we have SmartNet.
Can bandwidth be limited on end users and/or can they limit the ‘bandwidth rate limit’ to just youtube, steaming media, and downloads? If so, what should the limit be? and I’m assume this would be for ‘incoming’ traffic only? we’re running into some bandwidth hogs – usually youtube and/or streaming media. We have a Barracuda web filter which we’ve used to block and monitor activity but I simply do not have time to babysit this all day. I should also mention we do have critical data running up and down the pipe; such as credit card processing, DB replication between in house DB and hosted website, TPCx and EDI, FTP, and such that we don’t want restricted.
I have an issue where our ASA 5520 is impacting upload (from LAN to internet) speed. We have a 100Mbps SDSL internet link and only see around 45-50 Mbps on the upload when going via the firewall, download is around 90+ Mbps so that is acceptable. I have tested a laptop connected directly to the internet router and that give near on the 100Mbps up and down speeds, but if I put that laptop on the LAN or directly onto the firewall interface I only see 90Mbps down and 45Mbps up. I have check that the interface speeds/duplex on the firewall, switch and laptop are correct and also checked there are no errors on the ports. I also turned off the IPS and that made no difference. In addition I have checked the CPU during download/upload (max): CPU utilization for 5 seconds = 9%; 1 minute: 3%; 5 minutes: 1%
In theory the 5520 should be able to cope with this throughput:
Cisco ASA 5500 Series Model/License: 5520
Maximum firewall throughput (Mbps): 450 Mbps
Maximum firewall connections: 280,000
