CISCO 1721 :// No Echo/Response from CONSOLE Port

I have a CISCO 1721 I found in my 'stuff' when I was moving and I want to use it as a home router. Connecting to the CONSOLE port I get nothing echo'ed back. I confirmed connection hardware (USB=>Serial/Roll-Over cable, etc) by consoling into my CISCO 1841 lab router.
Other things I've tried are:
1) Wireshark'ed CONSOLE port - nothing;
2.) Wireshark'ed the AUX port - nothing;
3.) Wireshark'ed the ETH port - looks like 'normal' data.
I wanted to see if I could access the CONFIG from the AUX port by directly connecting my Laptop w/ a Roll-Over cable but not sure how to do that w/out a modem. Any suggestions from anyone??
Best regards....

The aux port is not restricted to use for modem. Depending on how the router is configured you might be able to start an exec session, get into privilege mode, and access the configuration of the router. I have been successful on similar routers connecting the console cable to the aux port and accessing the router.

I've got no response from serial port

Hi,i found sample source code from this forum to make communication to modem. I tried that code to make communication to cellular phone which is connected to serial port by data cable. There is no response at all from the phone. I'm confused, what's wrong with the code? But if i use hyper terminal on windows 2000 to send AT commands,the phone gives responds. FYI,i use Siemens C35i cellular phone. Is there someone who can tell me what's wrong with the code ?

the very first command you have to send to the modem is AT
wait 2 seconds then start sendind other commands

Is It possible connect two router**from console port to console port

Hi,
I need this for doing reverse telnet.
Thanks very much

No
you can connect router 1's aux port to router 2's console port.
line aux 0
password blablabla
login
modem InOut
transport input all
find the aux port's line number which depends on the router model then telnet to a live ip on router 1 on that port.
Worc_3640#sh line
Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int

Router 2911 - no repsonse from console port

I have a brand new cisco 2911 router but i am unable to console this router although i have configure terminal 9600 baud, 8 data bits, no pairty, 1 stop bit, no flow control. I also change the console to other computer but the result no change.
Please help me because i can not configure anything if i am unable to log in the router.
Tks,
Dzung

Do you have a different router/switch/... to test with? perhaps the console-cable is faulty.
As a workaround you could also use the usb-console that this device has. For that you need a standard USB-cable (like the one for a camera or a portable hard-disk) and the device-driver from cisco.com.

Thre is no response from WAE´s console

Hi,
I received 3 new appliances (02 WAVE274 and 01 WAVE574). All these equipments have the same problem: There is no response from console port.
I have a console cable that works fine in the console port of our router, but when I put this console cable in the right serial port of the WAE, there is no response from console (9600,8,N,1).
When I put a monitor in the video port I see the screen from a normal boot process (see the attached file).
There is no a configuration in these appliances. So, the telnet and web access is not enabled.
Could you please help me?
Thanks,
Teddy

Hi Teddy,
If you see somehting coming out of VGA port on directly connected display, which means the unit is booting up. If you connect the console, you should see the same bootup process. if you see the bootup process from VGA but not thru console, I suspect, it might be something with console cable or console settings.
Few options you may want to try:
1. Try using one of the cable that was shipped with WAVE device.
2. Try using differnet software. We use PUTTY on regular basis and it works fine with default settings.
3. Try changing console port settings to 9600 N 8 1 XON/XOFF
Hope this helps.
Regards.

Unable to access console port

Hi,
i was unable to access my cat6509 neither from console port or telnet access since someone by mistake has modified the setting in the switch &now it become inaccessible so is there any suggestion to workaround without losing my current configuration .
by the way when i connect to the concole port through terminal window nothing can by display in the terminal(blank)

Hi,
have you access to the MSFC?
I don't understand the problem, but this maybe could help you:

Received response from host (router IP address) with invalid source port 32784

I replaced my old wireless router with a Cisco Linksys E4200, running firmware version 1.0.02 build 13 May 24, 2011. About once a minute the router sends an unsolicited DNS message to the IPV4 multicast address 01:00:5e:00:00:fb with a destination IP address of 224.0.0.251. The unsolicited message is a DNS response with source port 32784, transaction ID 0, flags 0x8400 (standard query response, no error), questions 0, answer RRs 2, authority RRs 0 and additional RRs 1. The two answers both relate to the router itself: one has Name Cisco18738.local, type A (host address), class 1 (IN), cache flush true, time to live 1 minute, data length 4, and the address of the router. The other is the reverse of the same address. The additional record is for Cisco18738.local, type NSEC, class IN, cache flush true, time to live 1 minute, data length 5, next domain name Cisco18738.local, RR type A (host address).
When my desktop computer receives these messages it logs an error, for example: "Jun 23 07:39:22 sauterws02 avahi-daemon[1067]: Received response from host 10.146.9.1 with invalid source port 32784 on interface 'eth0.0'" The 10.146.9.1 is the router's IP address. I also see these messages on the wireless link from my laptop.
I suppose the E4200 is generating these DNS messages in a misguided attempt to make sure there is no old information about its name. Is there a way to turn them off? If not, is there a way to report this to Cisco as a bug?
Solved!

1. To contact Linksys, call support.
2. From the internet draft: "Multicast DNS implementations MUST
silently ignore any Multicast DNS Responses they receive where the
source UDP port is not 5353." Your avahi-daemon does not comply with this draft.
Thank you for the reference. For the sake of others who may read this thread, the current draft of multicast DNS is at http://www.ietf.org/id/draft-cheshire-dnsext-multicastdns-14.txt.
Here is the whole paragraph from which you quoted, from section 6 (Responding): "The source UDP port in all Multicast DNS Responses MUST be 5353 (the well-known port assigned to mDNS). Multicast DNS implementations MUST silently ignore any Multicast DNS Responses they receive where the source UDP port is not 5353."
Thus, it appears that there are two errors here: the Cisco E4200 is not using 5353 as the source port, and the logger is not silently ignoring it.
The message appears to be an announcement rather than an actual response to a query. In section 8.3 (Announcing) I found this paragraph: "A Multicast DNS Responder MUST NOT send announcements in the absence of information that its network connectivity may have changed in some relevant way. In particular, a Multicast DNS Responder MUST NOT send regular periodic announcements as a matter of course." Thus, it appears that there are three errors here.

One socket and two ports, not getting response from the server

Hi everyone,
I am working on device which communicate through Tcp sockets, It has an IP address and one port for listening and another for sending the response.
Problem is that I am able to create a connection to Device ip+port, and i am trying to listen on the same port while the device is sending the response on other port. My problem is that i can't create another socket using this port and therefore not getting the response from the device.
Can you people tell me how to handle such socket communication in java ?
Thanks in advance.

I am working on device which communicate through Tcp sockets, It has an IP address and one port for listening and another for sending the response.Are you sure? That's not usual. It would be usual for it to use the same port for listening, reading, and writing.
Problem is that I am able to create a connection to Device ip+port, and i am trying to listen on the same port while the device is sending the response on other port.I would try just reading from the same socket you are sending on. I suggest you have misunderstood how the device works.

No Responses from ALOM using NET MGNT PORT on SunFire v245

Please Help...
I have two sunfire V245 servers running Apache on Solaris 5.10. Both servers have the same settings and apps. Before we used serial port to connect to ALOM 1.6. We switched to net mgnt port because of virtualization of all our servers.
Situation:
Server 1 applied the solaris patches to server 1 and switch to Net Mgnt port to connect to ALOM and no problem setting up and connecting to ALOM. And it is still working and everything works fine.
Server 2 did not applied any solaris patches and switch to Net Mgnt port to connect to ALOM and no problem setting up and connecting to ALOM. After applying solaris patches to server 2 (same patches applied to Server 1), no responses from ALOM when connecting to it. Apache and Unix OS are both working fine. Just can not connect to ALOM.
Please Help ... many Thanks in advance
George

if you want to connect via net mgmt port, then you have to configure a separate IP address for net mgmt to access.
if you have not configure the IP for net mgmt then you can connect to serial mgmt port with a straight cable and with a DB-9 connector (null modem)
OR
you can do this from OS as well.
go to
login as root user
cd /usr/platform/`uname -i`
cd sbin
./scadm help
./scadm setsc netsc_ipaddr 0.0.0.0 (net mgmt IP, other than OS)
./scadm setsc netsc_ipnetmask 0.0.0.0
./scadm setsc netsc_ipgateway 0.0.0.0
./scadm reset-sc
plug in a cable in net mgmt port.
now u can access through net mgmt IP.
the proper way to exit from serial management is
sc> logout

Is it possible to use Cisco 1721 AUX port to dial into MS-RAS?

Which one is the console port of a cisco catalyst 500 express ?

i cant find it anywhere ?

jillesmiedema,
I haven't used that type of Cisco switch myself but did some research and it looks like there is no console port on this switch. It appears to be set up via a GUI application.
See this link...
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6545/product_data_sheet0900aecd80322aeb.html
which states this...
The Cisco Catalyst Express 500 Series switches are designed for ease of use. The switch is initialized through the GUI Device Manager; no console cable or terminal emulation application is needed
As far as help setting this switch up please see the following link which should get you started in the right direction...
http://www.cisco.com/en/US/docs/switches/lan/catalystexpress500/release_12.2_25_fy/quick/start/1708402.html
Hope this helps you out. Let us know how it goes.

for the first Server and EM Control port 1158
and 2nd is 5560
i want to run both the EM controls on 1158
Is it possible?How
i know we need to play with emom.properties but in sysman/admin
i see these files
emomslogging.properties.template

i dont which exactly is that file
and what entry we have to make?
Thanks

Catalyst switch hangs when connecting via console port

Hi,
I've just started work for a company - they have no network documentation or knowledge of their current set-up whatsoever.
For the LAN in the office they have Cisco Catalyst WS-C3524-XL switches. But it doesn't seem like these are even configured with an IP address for management purposes.
So, I thought I would connect via a console cable to have a look at their configurations and also to investigate some performance problems some users were having on the LAN.
BUT - when I connected to the console cable, all the switch LEDs stopped flickering happily and went solid and everyone in the office lost their network connectivity! (I wasn't popular!)
Rebooting the switch with the console port still connected had no effect - the LEDs remained solid and there was no network connectivity. However, when I removed my console cable, everything started working again!
Does anyone have any ideas a) what can have caused this and b) how I can resolve this problem and connect to the switches without disrupting all the other users!
Note: I subsequently connected to a spare WS-C3524-XL switch using the same laptop and same console cable without any problems.

Hi,
thanks for the response.
no, I can't login to the switch(es) at all. There seems to be no response from hyperterminal at all. (Then I noticed that the LEDs had gone "solid" and that everyone started to complain they had lost network connection!)
Even when I powered off and powered on the switch with the console port still connected, nothing appeared on the hyperterminal screen.
However, as mentioned, I'm able to connect to one of our spare switches using the same settings, same laptop, and same console cable - so I guess that would rule these things out as being the cause?
Its definitely a strange one, especially as it seems to be affecting all 3 of the live switches!

CRS Engine restarts every 2-3 days due to NOT_OK response from Watchdog

Hi,
we have 2 Cisco Unified IP IVR servers running version 7.0(1)SR03_Build011. Every 2-3 days, the CRS engine restarts at different times on both servers due to a Watchdog Thread received NOT_OK response from process CRS Engine.
These servers run independently of each other - (i.e not an HA pair) - but over the weekend, both servers had a CRS engine restart at the same time. I've looked at the MIVR and MCVD logs and they confirm this, but are so detailed, I can't actually still see what the cause is. There are a number of errors of different types, where the log seems to show a lot of 'exceptions', but it seems to lose connection to the Call Manager that causes the restart and it mentions buffer space.
We have a 3rd server which is not part of the solution that the other 2 servers provide, but it has the same OS, the same CRS application version and is connected to the same Call Manager; (version 6.1.3-200); but this server doesn't restart. It is on the same subnet as the other 2 servers.

Hi
If it happened to two servers at the same time then I'd be looking off box for problems.
- Check whether your CCMs were stable (use RTMT and check for events at the time)
- Run a 'show spanning-tree active detail | i VLAN|hange' or similar to check for STP topology changes on the VLAN the servers are in. Short outages caused by bad port configs in the VLAN can cause CCX/IPIVR to get upset briefly and fail over when communication between different processes on the same box fall over; it can be very sensitive. Maybe also do a show log on the switches to see whether any other significant events happened at the same time.

OOB management with console port

I would like to do the setup according to the doc - http://www.cisco.com/en/US/tech/tk801/tk36/technologies_tech_note09186a00800941c9.shtml
The only disadvantage I see is from the following excerpt from the article -
"Warning: Unprotected modems should not be connected to the console port. The console ports do not log users off when the carrier detect is lost, which can leave a security hole. To avoid this, use a secure modem, or connect via the AUX port. For more information on the advantages and disadvantages of connecting a modem to the Console port, refer to the Modem-Router Connection Guide."
I know I could set an exec-timeout of 1 minute but that would still leave a small window of time for security breaches if the line drops.
Could someone tell me a particular modem that has a password built into it to overcome this problem? What is the best security practice in this case?
I have setup modems before on the aux port, but you cannot access the router after reload if it boots into ROMMON mode for some reason.
Thanks,
RJ

Hi,
As a workaround you can try using an old junk PC with 2 serial ports, install Linux on that PC, connect via terminal session using the modem attached to serial COM1 (modem in autoanswer mode just like you're doing now), login with username/password on the Linux machine and then use a terminal emulation software like Minicom to open serial port COM2 to get the IOS prompt from the router.
Maybe this option is too much hassle for your application, but it won´t cost you a dime and is not really that difficult.
Regards.
