<title>4 byte AS numbers from ARIN</title>
<link>http://www.dslreports.com/forum/remark,20846384</link>
<description><![CDATA[Received this yesterday.  Does anyone have a list of cisco routers or IOS that will support this?

ARIN reminds the community that on 1 January 2009, all new Autonomous System Numbers (ASNs) issued will be four byte by default, unless otherwise requested. Following a globally coordinated policy, ARIN and all the Regional Internet Registries began allocating four-byte ASNs by request in January 2007; January 2009 marks the transition to allocating four-byte ASNs by default (see http://www.arin.net/policy/nrpm.html#five1).

Network operators may find themselves with a new four-byte ASN that upstream providers, peer networks, and customers cannot recognize. Without timely support from vendors, network operators risk having routers and network administration systems that will not accept the expanded four-byte number format. As such, ARIN urges operators to verify their vendors' routers will support four-byte ASNs.

To help vendors understand how to provide four-byte ASN support and to help network operators find products that support four-byte ASNs, APNIC has set up a special website at http://icons.apnic.net.

Please contact hostmaster@arin.net if you have any questions concerning the ASN policy and four-byte ASNs.

Regards,
Leslie Nobile
Director, Registration Services
American Registry for Internet Numbers

<title>Flapping PTP T1 on Cisco 1721&#x27;s</title>
<link>http://www.dslreports.com/forum/remark,20837023</link>
<description><![CDATA[This is driving me nuts! I have a PTP T1 between two Cisco 1721's, each with a WIC-DSU-T1 card (V1, not V2). Both sides have been configured with T1 defaults (ESF framing, b8zs linecoding, timeslots 1-24). One site is set to internal clock source, and one site is set to line, and both are configured for PPP encapsulation.

Now, I get calls from the contracted tech supporting these routers and he says the T1 goes down about once an hour for a period of about 15 seconds. When I remote in, I see lots of Input Errors, all in the form of CRC, Frame, Abort, Interface Reset and Carrier Transitions. Now, from experience and research, these are the steps I have taken to isolate the problem.

1) Performed numerous hardware loopback tests on each CSU/DSU using extended pings tests. All ping tests had 1500 byte sized packets, various datagram patterns (0xffff, 0x0000, 0x0101, etc), each test consisting of about 2500 pings. Both WIC's tested clean.
2) Had the contracted tech test each cable, both came back 100%. They are solid copper shielded twisted pair, about 10 feet a piece.
3) Had the telco do their tests. Don't know what they did but they claim they are clean on their side.

Cisco's serial line troubleshooting doc indicates that these errors are produced from mismatching is framing and clocking configurations, or bad cards, or bad cables, etc. I have eliminated all of these as a possible cause. I cannot seem to track down the cause. When I do test and stress the circuit, I cannot reproduce any errors.

Any ideas as to what I am missing? Do I need to specify the clock rate on the router that is set to internal clocking?]]></description>

<title>Cisco VPN Client question</title>
<link>http://www.dslreports.com/forum/remark,20835778</link>
<description><![CDATA[Has Cisco moved forward at all with developing a Windows 64bit VPN Client yet?

I am getting either a Dell D830 or M6300 notebook with 8GB of RAM and I don't really want to be installing VMware and XP 32bit just to be able to access Cisco VPN sites. 

Thanks
Leathal]]></description>

<title>CCNP Bootcamp recomendations?</title>
<link>http://www.dslreports.com/forum/remark,20832584</link>
<description><![CDATA[Hi Guys,

I just got my ccna earlier this week and I wanted to try for my ccnp soon.  So I'm looking for recommendations on ccnp boot camps, in specific the routing and switching specialization.  

The company is picking up the tab on training so cost isn't a huge concern.  I would like the training center to be located in a nice place my mind can relax so I can learn.

I realize this is an odd request but I thought I would ask if anyone knew of such a place.  I tried the "training camp" already but the next class they only offer is in northern IL.  Not really conducive to learning.. 

Thanks

<title>[H/W] Cisco ASA 5505 stops accepting outside traffic</title>
<link>http://www.dslreports.com/forum/remark,20845652</link>
<description><![CDATA[Good evening...

Tonight i was down at my colocation facility trying to replace my Watchguard Firewall with a brand new Cisco ASA 5505 I picked up off of Amazon

Things went smoothly until all of a sudden the 5505 stopped accepting outside traffic (web page views or pings)...

Logged into the ASDM, it was reporting all connections "up", and the log wasn't showing anything unusual, but none the less, anything outside the network was getting nothing...  rebooting (unplug and replug, also teleneted in and did "shut" and "no shut" on the external interface) fixed it for a little while, and then it eventually went back to the problem

What would help you others to help me?   Posting part of my config file?  looking in the log file for something particular?

I'm new to the whole Cisco family, so any guidance to make this easier to get help would be appreciated

Thanks in advance]]></description>

<title>[Config] SDM installation issues on 871</title>
<link>http://www.dslreports.com/forum/remark,20847274</link>
<description><![CDATA[I'm having a real strange issue with my 871w. I had the full SDM installed on it, but was running a older version. I got SDM v25 and started to do a re-install. The installation package successfully downloaded the old config and make a sdm backup on my system, but something really is messed up with the rest of the install.

I am selecting to install SDM and WLAN packages and the install starts, I can serial to the router and doing a dir of flash, I watch the tar'd files slowly get uploaded to the router, the first time I tried it, home.tar, common.tar, es.tar, sdm.tar and the config files successfully made it to the router, but it just sat forever trying to upload the wlan package. About 30% of it made it t flash (judging by file size). But it would never finish, the sdm install app just hangs.

I had to reboot to abort it, and obviously running it a 2nd time, there was not enough flash space left to try to re-install it, so I manually deleted all the files from flash, and attempted to run the install again, now every-time (I've tried 5 or 6 times) it bombs out and gets hung during the sdm.tar copy to the flash. I actually left it running for a week while I went on vacation, but it never completed.

Im stuck with a router that I can start to HTTP connect to, it loads like its going to load SDM, but when it comes to executing the sdm package, it gives a execute permissions incorrect (the file isnt there is the real issue).

Anyone seen this? I dont know enough about cisco to attempt to do too much by myself, but I do have TFTP on the machine, and can transfer files manually, but I really need assistance, I would hope to get the setup to work.

Thanks in advance.]]></description>

<title>Voice moudle EM-HDA-6FXO</title>
<link>http://www.dslreports.com/forum/remark,20846721</link>
<description><![CDATA[Kindly assist me with a clarification on the above voice module. The Customer ordered a Cisco2821-ccme/k9 router with a EM-HDA-6FXO voice module. However, they only got a Circuit Board with no face plate to connect an RJ21 connector from the Telco side (see link). Is this how this voice module ships ?

<title>[CCNA] Online CCNA Training</title>
<link>http://www.dslreports.com/forum/remark,20842755</link>
<description><![CDATA[Hello everyone, I'm in the process of preparing myself for taking the CCNA.  I have a fairly good background in configuration, testing and troubleshooting Cisco and network related issues.  I'm looking for a good online resource for CCNA training, I would like it to be instructor led but self paced is good as well.  I'm also willing to pay, but I'm not looking for a boot camp type course, mainly I'm just looking for some kind of structured environment.  If anyone has any suggestions please let me know.  Thank you very much.]]></description>
