Cisco Firewall :: ASA 5505 ROMmon After Erase Flash?

Oct 19, 2012

I was trying to erase some bad test configs on my 5505 with a write erase, but all VLAN and Ethernet configs remained.  I hastily decided to do an erase flash.  No I'm stuck at a ROMMON prompt with no image found to boot I'm hoping I don't have to TFTP a factory image.  How do I find the images on disk0 and copy them?

Cisco Switching/Routing :: Cannot Get Out Of Rommon Mode 1760

Dec 10, 2011

I'm currently pursuing to take my CCNA and am currently studying for it, but have recently encountered a problem with one of my 1760 routers that I can not solve.Yesterday I went to boot up my router like normal, however when I went into hyperterminal I noticed the router was in Rommon mode. Thinking I could change the configuration registry, I tried to bypass the NVRAM by using confreg 0x2142. However this still causes the router to go into Rommon mode. I am getting an error that states that there is insufficient memory to load the IOS image. [code]
 
I have used the dir flash: command and can see the IOS image, and try to boot from it (boot flash:iosimagename) but it will still go back into rommon mode. I also just swapped the RAM from my other 1760 into this 1760 and it booted up and went into normal configuraiton mode without any issues. However, the other router now will not load it's IOS image and I get the exact same error.I'm at a loss here, and have searched to figure out where or how I can just wipe the router clean to try and start fresh, but cannot get out or Rommon mode. The only thing I can think of is that the RAM went bad since it wont boot up either machine.

Cisco WAN :: Management Port In ROMmon Mode - ASR1002

Cisco Firewall :: Is It Possible For 5505 ASA To Be In Transparent Mode

Feb 20, 2013

Is it possible for an 5505 ASA to be in transparent mode such as ethernet0/0 outside, ethernet 0/1 inside, and use ethernet 0/2 for syslog only on a seperate network other than the one that 0/0 and 0/1 is using.  The tranparent part being on a 192.168.168.X/24 and the syslog server being on say a 10.2.1.X/24 network?

Cisco Firewall :: ASA 5505 - Transparent Mode

Sep 15, 2012

I just have 1 question. I am going to be getting U Verse installed at my house and have been having a hard time finding this in the documentation. The modem I am going to be getting is the 3800HGV-B. Over on the ATT forum users are stating that the modem needs every MAC of every potential IP. I thought about using it's DMZ Plus mode but I am getting a block of 8 IP's and it doesn't seem to play nice unless it see's 5 different MAC's. Right now I have my 5505 in routed mode so I don't believe it passes the MAC of the client's through. Will the ASA pass the MAC of the client's through to the modem with the appropriate ACL's applied?

Cisco Switching/Routing :: 3550 - Copy IOS To Switch In ROMmon Mode?

Jan 24, 2012

I have a 3550 switch that was replaced at a remote site with no IOS. This is a switch not a router so tftpdnld does not work.
 
[Code]...
 
The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
 
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.

Cisco Firewall :: ASA 5505 In Transparent Mode Traffic?

Oct 23, 2011

I've  setup my Cisco ASA 5505 in transparent mode. I have a Cisco 1841  connecting to the ISP (DHCP client) and F0/0 for inside. The 1841 is the  DHCP server.  I have my ASA 5505 behind the 1841 in transparent mode  (Vlan 1 for Outside and Vlan 1 for inside). The router config is  good as when you connect a computer straight to the inside interface I  get DHCP and can go to internet, no problems what so ever. But When  you're trying to go through ASA isn't not working.  if I add a ip any any statement to the access list it will work but  having an "ip any any" in a access list is like having no firewall at  all.

ciscoasa(config)# sh run

Cisco :: 2951 - Access Server Not Displaying ROMmon Mode Target Device

Sep 17, 2012

I'm configuring a console server for configuring remote devices. This is working well except for the fact that if a target device is in ROMMON mode, the console server refuses to displays the target device console. It does open the connection but the ROMMON prompt is not shown on the console server . This is essential for this device as we will need to use it to reset passwords remotely and thus need to be able to access ROMMON mode from the console server.

Parts used are a 2951 router and a HWIC-8A serial card. Posted my config below:

Current configuration : 4389 bytes

Cisco Firewall :: ASA 5505 Transparent Mode And Management Access

Apr 26, 2012

I have a need to manage the 5505 outside of the 2 interfaces however I see it documented that Management access is only via the data path interface. This won't work for me because there will be NO management access on the data network being bridged through the firewall. Is there any option outside of going to routed mode or moving to the 5510?

Cisco Firewall :: ASA5510 Single Mode / Move To Multi Context Mode

Sep 16, 2012

I got an ASA 5510 system currently in single context mode, with CSC SSM installed. Single ISP uplink to internet, no VPN. And now customer would like add another ISP uplink, without invest another box for HA.What come across my mind is make the current box into multi context. There's some area i need to concern and also need yours perspective on it.
 
Question 1: For making the firewall into multi context, am i need to do it from scratch, issue mode multiple command. Then rebuilt the current production config into one of the context, then another context meant for the new IPS uplink, and one admin context?
 
Question 2: For CSC -SSM licensing requirement, model ASA 5510 with security plus license is able to support 2 context. So if i split my firewall like what i mention in question, what exactly number of context do i own (admin, context A, context B)?
 
Question 3: For CSC-SSM module in multi context mode, so the management port of CSC SSM must attach at admin context?
 
Question 4: After configured all the policy and traffic to scan, how exactly i should do in order apply this policy to the interface?  Should i only enable at admin context, then firewall service-policy rules, and apply it global, OR should i also do the same action on context A and Context B?
