Cisco WAN :: 3750G LC To SC Conversion

Nov 1, 2011

I have a core switch Cisco3750G with 4 SFP slot populated with GLC-SX-MM module.Now in these 4 fiber GLC-SX-MM modules 3 are connected to 3 floor switches which are having the same GLC-SX-MM.Each link is configured as a TRUNK and allowed only that floor VLAN and working fine.Now the 4th GLC-SX-MM module has to be connected to a single desk top PC using a FIBER to UTP convereter,which is SC to UTP .Now patch pannel is LC ,I used a LC to SC fiber patch cord,but link is not coming up,in this situation if I used both side SC convereter then link is up.
 
All 4th GLC-SX-MM modules are checked and it is working fine.Only the forth floor link is not coming up,if I use the UTP to Fiber SC type connector in the CORE switch for teh 4th Floor then it is working.How to resolve this issue,Whether I need to use the UTP to Fiber LC type convereter in the fourth floor instead of SC type converter,logically when I use the LC-SC type patch cord and connecting to SC type converter it should work.

Cisco Firewall :: ASA NAT 8.x To 8.4 Conversion?

Jun 13, 2011

I have 8.2 configuration that works:
 
global (inside) 1 192.168.1.1
nat (outside) 1 access-list Servers outside
static (inside,outside) 10.16.0.0 10.1.0.0 netmask 255.255.0.0

[Code]....
 
It is remote monitoring ASA, so I need to nat user networks (10.1.x.y, 10.2.x.y) to something that I can use (10.16.x.y, 10.17.x.y...)
 
Also, since it my device, I have them configure snmp and syslog server on client's network to use 192.168.1.1, so I have dynamic NAT for two SNMP servers and static NAT for one of them (which is syslog server).
 
create 8.4 version, so I can apply it? I tried few things, packet tracer shows that they are NATed, but I have only Denc packets, because hosts see request coming from my public IP...

Cisco :: NAT / Unicast To Multicast Conversion?

Feb 8, 2013

I am planning to get the unicast streams from different 2-3 sources over internet, and I am doing NAT for port-forwarding all those unicast streams to a one private IP. Attached is the setup for your understanding.Setup: - Both unicast streams will be hitting to One Public IP (3.3.3.2) on UDP/TCP Port 1234, 1236 & 1238 only & the same ports need to be forwarded to natted One Private IP (10.10.10.4)

1)NATTING these 2 unicast streams into one private IP(10.10.10.4) by checking Source & Destination based IPs and ports, but in below configuration I cannot achieve on checking Source & Destination based IPs and ports

Router configuration:-

interface GigabitEthernet0/0
description ***Connected to Internet ***
ip address 3.3.3.2 255.255.255.252
no ip redirects
no ip unreachables

Cisco VPN :: 3060 - ASA 5520 Conversion

Sep 24, 2012

We are about ready to embark on moving all L2L and network extensions (Cisco ASA 5505s) from the Cisco VPN 3060 Concentrator to a Cisco ASA 5520. We would like to know if there is a simple method to doing this such as a converter?  Also, are there any lessons learned?  We are running 8.4.3 so we know that NAT configuration has differed.  Can the configuration from the 3060 be modified in anyway in configuring the ASA?

Cisco Firewall :: NAT Command Conversion PIX 6.3 To ASA 8.4(2)

Dec 28, 2011

I am in the process of migrating a production firewall from PIX 6.3 to ASA 8.4(2). This is going to be a complete firewall rebuild and I will not be upgrading the configs because they have become out of date and very bloated. I am in the process of converting the NAT commands.[code] I am hoping these commands would be enough to replicate the previous functionality. I removed all the static identity NATs because NAT control is no longer in place so those rules are not required. Additionally I didn't re-create the rules that had NAT ID 0 or 1 because it didn't look like they were doing anything. correct way to do the static NAT commands at the bottom.

Wireless To Ethernet Signal Conversion?

Jul 16, 2012

I need to get a connection through a 3 storie structure.

On each floor, I have a cluster of servers set up. Conventionally, I would thread cat6 cables through the building but due to various reasons I cannot do that.

On the ground floor there are 2 ground lines which project a wireless signal.

I'm wondering, is there some way I can convert the wireless signal into an ethernet line? Perhaps through some kind of interfaced adapter. I've thought of buying a throwaway laptop and bridging the connections manually but I'd prefer to avoid that option if there are feasiable alternatives.

Cisco Firewall :: Naming Conversion Is Not Happening In ASA 5520?

Nov 29, 2012

We have three Cisco ASA 5520 with 8.2 code in each tower. There are many configuration on the device hence we are using ip to Name to identify the naming conversion. Out of three one firewall naming conversion is not working, I mean after adding name for a IP it is not reflecting vpn tunnels or access lists or Nat config.

Cisco Wireless :: AIR-AP1220B Lightweight Conversion / WLC Support?

Mar 24, 2013

Is AP 1220B (b-only radio) supported for registration to WLC (7.0.x) with Lightweight software? I've managed to convert the AP to Lightweight mode, but I could not get it to register with WLC 2504 (software version 7.0). Is it possible that this AP is only supported if changing the in-built radio module?
 
In the compatibility matrix [URL] there is an information that this AP is supported on WLC up to version 7.0.x. On the other hand it is not supported by Autonomous to Lightweight Mode Upgrade Tool [URL] Since these APs does not have pre-installed MIC, it is mandatory for them to create Self-Signed Certificate (SSC). Upgrade tool could do this job (along with adding the created SSC hash to the authorized list on WLC), but it does not support this particular AP/radio. If I do the conversion manually (archive download-sw ...), the AP does not have the SSC needed for communication with WLC. I've tried making the SSC manually (instructions found on this site [URL] while AP is autonomous mode, and then converting it to Lightweight, but the AP still could not register to WLC.

In the debugs (on WLC/AP), I am receiving an error that is described in some Cisco troubleshooting documents as something related to WLC not having an SSC hash in the auth list. Problem is that the AP is not even sending standard CAPWAP messages and there is nothing to be seen in "debug pm pki enable" on WLC...

Cisco Firewall :: 6509 - FWSM To ASASM Object Conversion

Nov 4, 2012

We are in the process of migrating to the ASA service modules on both our 6509E switches from our current FWSM. We have used the Cisco conversion tool and applied that to the service module. When viewing the context in ASDM we are unable to view the object names in the right hand pane.
 
On the FWSM I would see the following under Network Objects:
 
Network Objects
- JQ-Test
- JQ-Test2
- JQ-Test3
 
Network Object Group
+ JQ Group
      - JQ-Test
      - JQ-Test2
      - JQ-Test3
 
Now I have run the conversion tool and applied that to the ASA's I now get the following results.
 
Network Objects
- 10.1.1.1
- 10.2.2.2
- 10.3.3.3
 
Network Object Group
+ JQ Group
     - 10.1.1.1
     - 10.2.2.2
     - 10.3.3.3
 
I am aware that the naming convention on the ASA's are different to the FWSM as you can no longer use the "name 1.1.1.1 JQ-Test1" format but I was hoping that the conversion tool would do this for me.
 
Is there any way I can get the names of the object back without having to script something that takes the old FWSM format and convert it into an ASA format?

Cisco Wireless :: LWAPP Mode To Autonomous Conversion Aironet 1262

Mar 13, 2013

we have 1262 (AIR-LAP1262N-E-K9) and we dont have WLC..and i want to convert it to Autonomous mode..i did the below steps... with using this file  (ap3g1-k9w7-tar.152-2.JB.tar) download it from Cisco site. Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30. Step 2 Make  sure that the PC contains the access point image file (such as  c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP  server folder and that the TFTP server is activated. Step 3 Set the timeout value on the TFTP server to 30 seconds. Step 4 On the PC where the TFTP server is located, perform these steps.

Cisco Switching/Routing :: Catalyst 3550 / IOS Naming Format Conversion

Jun 11, 2012

correlates the older IOS format naming compared with the newer? I have an older catalyst 3550 that might need an IOS upgrade due to us starting to implement dot1x. The reason that I say this is that some of the commands in the dot1x config guide, such as aaa accounting dot1x, are not valid on this platform. The current IOS is c3550-i5q3l2-mz.121-8.EA1c but the newer format is the ipbase, ipservices, etc. format. There is a newer ios but how do I convert from one to the other? I think I need to research the IOS to see if the new commands are there as well as I want to make sure there are no gotchas from a hardware standpoint if I upgrade.

Cisco Switching/Routing :: 6500 How Long Conversion Process Takes Place

We will be converting two 6500s to VSS. Each chassis has a Sup2T module, fwsm, 6908-10G blade, wism1 blades and two or three 6748-SFP blades. I was wondering how long the conversion process takes?  If I remember correctly at the 2012 networkers lab it took maybe 10 minutes while using Sup720s.  The instructor mentioned that with Sup2Ts it would convert a lot faster.
