However i cannot break into teh IOS in Hyperterminal using Ctrl-Break either as it boots or after teh IOS image has loaded (after it shows Decompressed image {ok} etc). I have tried several break key combinations such as ctrl+F6+break and they dont work either. On boot the unit does show Password recovery Functionality is disabled. IOS image is 12.4(13r)T.

During the day, both Internal calls over the MPLS and external calls over the ISDN break up, but it doesnt happen all the time, i.e in a day the morning will be ok, then the users experience the break ups in the afternoon, then its everything is ok again.
The only factor that the calls share is the Lan infrastructure i.e the 3750G switches (7) of them which are stacked.We did have MAC flapping errors, and our telecoms provider suggested that it maybe these causing the issues, however we have got rid of all MAC flap errors, and are still receiving voice break ups.
Because the Lan switches are the only "item" both calls share, I am wondering now if the setup of the switches is correct. [code]
I have over 20 units doing the same thing and it seems to be a software isssue but i dont see any bugs or posts on it. This is only on 2960S switches and not 2960 or 2960G units.
If i use the password reset feature to break the units into rom and then type "boot" instead of power cycling the unit, they will fail MBIST post tests. If the unit is power cycled or left to boot normally on its own, there is no issues and all post tests pass. I know MBIST is Memory Built In Self Test and was thinking maybe breaking the unit into rom disrupts those memory tests for some reason. I tried the following software and got the same results with all of the images:
122-55.SE2
122-55.SE
122-53.SE2
122-53.SE1
Logs attached are from the same switch, one with password reset procedure used and while left to boot on its own.
I have Cisco ASA 5510 series router which was handling by our one of our network admin who left without giving admin password. Now this is time to break the password . Since i don't know the admin password of the router , i don't how to handle few request. I am not a basically network admin guy to handle such things but i need to know how to break the password in order to do further requests. How to login router admin console without password or any chance to bring into default factory configuration.?
View 1 Replies View RelatedI am trying to come up with a standard way to configure controllers for my field guys. I'd like to just have them paste in a config that has all the settings, like we use to be able to do on aIOS. I am not seeing away to break out of the wizard so that they can just paste in a config. Do you have to go through the wizard in order to get to a CLI ?

My problem is that I am unable to break into ROMMON using the break sequence Ctrl + Break (as there is no break key). I have also tried TeraTerm with the break sequence of Alt + B.
Additionally, I have tried setting the baud rate to 2600 and pressing the space bar for 10 seconds to no avail.
when I may need to break into ROMMON.
I play the game with WiFi link with, however, less than 5 minutes to play will break why? All games are like that.

we have the following setup for our network :
UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs.. which is strange cause this is directly connected to it via ethernet cable.
I was asked to enable netflow in an ASA Firewall for Orion/Solarwinds server monitoration. Firewall is a 5550, with 4G RAM, and no extra modules but SSM-4GE. This firewall has 5 DMZ segments and ans specific segment for internet traffic.There are segments as unique subinterfaces in physical interfaces. Other segments as individual subinterfaces in the same physical interface (but individual VLANs)Usually firewall CPU flows between 30% to 40%. Rarely to 50%.
1 - How dangerous or risky could be implement netflow in this firewall?...This firewall is very critical for the customer. My concern is regrading CPU, traffic generated, memory, etc
2 - In a month, firewall will be migrated from 8.2 software version to 8.4 software version. Is there any incompatibility in some commands?...Would be recommended to perform netflow configuration after software upgrade?
3 - How could it be implemented for Orion monitoring, regarding each individual sub-interface (and so, each VLAN assigned)?I there any recommendation regarding configuration, best practices?
I have some problem with the ASA 5510 ver 7.0(6). My manager wants to keep this as backup. tried lots of things but still users not able to access internet nor can i ping anywhere.For example when i ping 4.2.2.2 i dont get any reply.The runing config is below for ur ref :

I have a normal setup of ASA5505 (without security license) connected behind an internet router. From the ASA5505 console I can ping the Internet. However, users behind the Firewall on the internal LAN, cannot ping the Internet even though NATing is configured. The users can ping the Inside interface of the Firewall so there is no internal reachability problem. In addition, I noticed that the NAT inside access list is not having any hit counts at all when users are trying to reach the internet.
When i replace the ASA5505 with a router with NAT overload configuration on it, the setup works normally and users are able to browse the internet.
The ASA5505 configuration is shown below.

setting up an ASA 5505 to be used as a firewall between a BT internet router(BTNet service) and a Cisco 3560 Lan switch. BT have presented me with a cisco 3800 series router with the following details:
Network Address Network Mask BTnet NTE Router LAN Address
There are 2 Gigethernet ports on the back of the router port Ge0/0 is connected to the BT NTE and the status light is flashing green. Int ge0/1 is connected into port int e0/1 of the ASA but i am unable to get any connection.
Internet ISP -> Juniper SRX 210 Ge-0/0/0
Juniper fe0/0/2 -> Cisco ASA 5505
Cisco ASA 5505 - >Inernal LAN switch.
1. Internet is connected to Juniper Ge0/0/0 via /30 IP.
2. Juniper fe0/0/2 port is configured as inet port and configured the Internal public LAN pool provided by the ISP. And this port is directly connected to Cisco ASA 5505 E0/0. Its a /28 pool IP address. This interface is configured as outside and security level set to 0.
From Juniper SRX, am able to ping public Internet IPs (8.8.8.8).
Issue:
1. From ASA am unable to ping public ip configured on Juniper G0/0/0 port.(/30)
2. From ASA no other Public internet IP is pinging.
Troubleshooting Done so far.
1, Configured icmp inspection on ASA.
2. Used the packet tracer in ASA, it shows the packet is flowing outside without a drop.
3. Allowed all services in untrust zone in bound traffic in Juniper SRX.
4. Viewed the logs when I was trying the ping 8.8.8.8 in ASA. It says "Tear down ICMP connection for faddrr **** gaddr **
We have a wifi network for guests, that we route to internet through an old PIX515 Firewall. We recently tuned the timers to lower values in order to "save" on resources and publix address usage.
The timers we use are:
-timeout xlate 0:30:00
-timeout conn 0:30:00 half-closed 0:05:00 udp 0:02:00 icmp 0:00:02
Through verifying the new timers, we noticed at some xlate connections (TCP PAT) that are idle for ever!!In the connection table, I cannot find an idle connection for longer than 1h....
I can't find the problem in firewall..

I called ISP to check,when ISP clear their router's ARP, the asa will lose the connection at the same time and then the ISP's router couldn't learn the ASA's MAC. After I 'clear arp' manually,The ISP's router can learn the ASA's MAC and the connection recovered,but the DMZ's cann't access internet still (of course,There is no problem between DMZ and ASA ,I ping the internet gateway from DMZ host and can not get any reply.).
WE have a DMZ on ASA5510 8.4, it can access anything internal interface but cannot get out to internet or outside interface. I try to ping from a host in the DMZ to 8.8.8.8 and get this in the log 6Apr 25 201208:24:431100038.8.8.80172.10.1.1501Routing failed to locate next hop for ICMP from outside:8.8.8.8/0 to inside:172.10.1.150/1.

View 14 Replies View RelatedI have a server with IP address 10.10.10.10/24. I have two ISPs and their public IP address subnets are 1.1.1.0/25 and 2.2.2.0/25. The gateways are ASA 8.0 and ASA 8.4.I am getting rid of the 1.1.1.0/25 ISP. However I will need the Internet users to be able to access the server via both ISPs at the same time.The only way I can think of is to do policy based dynamic PAT so the Internet user IPs will be translated into an internal IP. Idealy, users connecting on 1.1.1.10 will be PAT to 10.1.1.10 and users connecting to 2.2.2.10 will be PAT to 10.2.2.10. When the server responds to them, it will then route to the correct ASA..

I cant find anything definitive on google to say it will or wont, i know it cant do policy based routing.
I have basically started fresh, from a clean image. We bought these with the expectation that we would be able to configure them using the GUI for what we need, which up till this point doesn’t seem to be the case.I will tell you how I have this setup, I have our ADSL going to a modem acting as a bridge with a static IP supplied by the ISP. If i connect a laptop to that modem and set the static ip on the laptop, I get internet access fine.So I then connect the modem to ethernet0/0 and the laptop to ethernet 0/1 I connect to the ASDM and run the startup wizard with the following:
· Outside ip : 87.87.87.87 255.255.252.0 (this works on the lappy straight to the modem)
· Inside ip : 192.168.10.1 255.255.255.0
· No dmz

I am updating my 8.2(3) code for my new ASA5512 that is running 8.6(1) and am unable to get on the internet with my current configuration from the inside interface.

I've created a DMZ on ASA5510, it can access anything internal but cannot get out to internet. I cannot manage the ASA from the DMZ subnet neither.
