Cisco WAN :: Telnet Access Through Router 3925 Not Working?
Feb 18, 2013i have 68 sites with Routers. On each site I have one equipment DIRECTLY connected to the Router that needs to be accessed by telnet port 23.
I have 15 off this sites that the access via telnet to the equipment’s connected after the routers are not working. These sites are using Router Cisco 3925. The other sites that are working are using Routers Cisco MWR 2921.
Both router models are running the same configuration with no filter on it.
The equipment’s after the routers are all accessed directly via telnet without the router. If the router is directly plugged to the equipment the 15 sites with Router Cisco 3925 are not accessed via telnet.
There is any bug related with the IOS version that Router Cisco 3925 is using?:
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.1(2)T2, RELEASE SOFTWARE (fc1).ROM: System Bootstrap, Version 15.0(1r)M8, RELEASE SOFTWARE (fc1).System image file is "flash0:c3900-universalk9-mz.SPA.151-2.T2.bin"

Mar 31, 2013implementation of the cisco CSS 11501 boxes available as spare on our site into production for an application evry thing worked as expected. i was able to telnet the active/master box and was able to console both master and backup box from the console port.however a week post the activity im faced with this weird problem where im not able to take console or the telnet access of my primary/active box.The boxes are working in BOX-to-BOX redundancy and now im not able to telnet or console my active/master box. The telnet and console window prompts me for username and password and after entering the credentials nothing happens. no prompt or no error message is displayed.
The telnet primary authentication is via tacacs and secondary is via local. however for console im not using any method for primay authentication and local for secondary authentication. however i can successfully console my backup box. below are my obsrvations 1. the left and right status LED on the active CSS box is OFF.- it means my CSS 11501 failed and has no power. 2. upon firing the rcmd command with show line command on backup box i see that the telnet sessions and console session is established with the master box3. the redundancy state of the active box says it is master and has not changed state since my last activity, no application issue reported, all the services are active on the active box and also i can ping the active box ip address from my backup box over which box to box redundancy is established. This confirms the active box is functioning well 4. i initially thought the telnet sessions are not getting cleared, however the show line cmd with the rcmd cmd on the backup box confirms this is not happening. now im stuck as the active box cannot be accessed at all via console or telnet. i was thinking of below steps to be carried out.1. to failover the boxes and make the backup as master2. then try to take the faulty box off the network and troubleshoot (are there any other commands that i should use to troubleshoot)3. if nothing works try rebooting the box and check
NOTE: the software running is version 7.20.30.3 with standard feature set. we are not using cvdm or the CSS GUI. we could access the css initially on CSS gui and that is also not working now.
Cisco WAN :: 861 SSH / Telnet Privilege Exec Level 15 Enable Not Working?
Aug 10, 2011I have a customer with a 861 ISR.I want to block all the privilege 0 users from access the enable command
If i telnet into the device, as a priv=0, enable does not work
If i telnet into the device, as a priv=15, enable does work
If i telnet into the device, as a priv=0, enable does not work
If i telnet into the device, as a priv=15, enable does not work
I have issued the command:privilege exec level 15 enable Should block everyone except 15's from accessing the enable command SSH and TELNET are on the same vty:
line con 0
login authentication local_authen
no modem enable
line aux 0
line vty 0 3
[code]....
Basically TELNET is following the rules ( priv=0 not allowed to access enable ) but SSH is not following the rules ( both priv=15 and priv=0 cannot access the command ) is there a way from blocking somes users from login in completely?

Nov 13, 2011I have a question regarding the 3925 router. In the past on my old 3660's, in order to add a new line to an ACL, I would have to remove the entire ACL and readd it when adding new ACL lines to the list. Is this required on the 3925's, or is it like the ASA 5520's where you can just add an ACL any 'ol time without having to remove/add the entire ACL list?

View 1 Replies View RelatedCisco WAN :: 3925 Connected To Internet For VPN Backup
Mar 10, 2013I am trying to set up a redundant OSPF setup and I am seeing behavior I don't quite understand. At the main office I have two routers, a 3825 connected via full DS3 to the MPLS cloud, and a 3925 connected to the Internet for VPN backup.There are nine branches, but I am only going to talk about three. The three branches all connect together as well as having their own MPLS connections to the cloud. They are all 2821 routers with a 4.5 Mbps multilink interface into the cloud (three T1's). One of the branches has a backup IPSec/GRE Internet connection that I want any of them to be able to use in case of an MPLS problem (which there have been many lately, sometimes involving all of them going down at the same time). The connection into MPLS uses Inter-area OSPF with the provider. The Tunnel connection is also using IA OSPF (the main office is area 0 and this cluster of branches are all on area 100).
OSPF seems to be behaving oddly. At the main office, on the 3825 with the "backup" shut off, if I do "show ip route 10.51.0.0" it shows this output: [code]If the metric before was 24, why would it put in a route with a metric of 53 now? What's worse is that the branches all think they should connect over the MPLS and the main office sends everything over the VPN. It works, but I don't really want asymetric routing! I have included some configs as well... those which I consider relevant. I am including a diagram that has more on it than is relevant, but what I referenced is here (and yes, spanning-tree has been properly configured on the red fiber connections with the connection between FEC2960 and Hl2960 blocking, but try to ignore the LAN stuff because this is in a transitional phase right now anyway).

Cisco :: 3925 H.323 Monitor Via SNMP (Solarwinds)
Apr 9, 2013Monitoring H.323? I've got a 3925 running15.1(3)T with 9 PRI's. Because of our volume, syslogging is not the desired solution. We want something that we can potentially graph over an 8 hour period, so while the RTMT is accurate, either it won't store the data for 8 hours, or we aren't using it correctly (plus, mgmt may want access to the stats/graphs, and we're not keen on granting them access). So far, we've used: [code] None of these seem to accurately portray utilization. cdsp Active Channels seems to get the closest, so perhaps I have to tweak it a little bit, but so far, nothing accurate.

Anyway taing a closer look at E1 lines and had some questions:-
Microwave radios E1 circuits are set to UNFRAMED, router interfaces set to NO-CRC4, didnt think this was the same?

I have set GBethernet 0/0 to 10.0.1.1 / 255.255.255.0 and GBethernet 0/1 to 10.0.2.1 / 255.255.255.0. I have set a static route 0.0.0.0 / 0.0.0.0 to 10.0.1.21 for gateway of last resort.
When I setup a workstation on the 10.0.2.X segment at 10.0.2.100 wirh a gateway of 10.0.2.1, I can ping 10.0.2.1 and 10.0.1.1 but can not ping anything else on the 10.0.1.X network or on the internet. When I am connected to the console port on the router I can ping 10.0.1.1 and 10.0.2.1 and 10.0.1.21 and any address in the internet but I can not ping 10.0.2.100.
When I am on a network connected to the 10.0.1.x network af 10.0.1.100 I can ping 10.0.1.1 and 10.0.2.1 and 10.0.1.21 and anywhere on the internet but can not ping 10.0.2.100 or any other address on the 10.0.2.x network other than 10.0.2.1.

The Cisco enhanced EtherSwitch service modules also provide a physical Gigabit Ethernet serializer/deserializer integrated circuit transceiver (HIMI) interface. In the Cisco 2900 series and Cisco 3900 series routers, the HIMI link on the Cisco enhanced EtherSwitch service modules is connected to the router internal Gigabit Ethernet backplane. This link is used for interconnection between other interface cards or network modules attached to the router Gigabit Ethernet backplane bypassing the router host CPU; thus, increasing CPU performance by decreasing CPU processing.
