Cisco :: LMS 3.2 DFM Devices Stuck In Learning Mode

Jul 10, 2011

I'm having problem with DFM under LMS 3.2. For some reason it periodically loses discovered devices and put all of them into "Learining" state. Sometimes restarting daemon manager useful but now it doesn't. I tried rediscovery few times but it doesn't work at all.

Cisco :: LMS 4.2 - DFM Devices Stuck In Learning State

Apr 15, 2012

Why this same kind of bug/error/software fault exist in LMS 4.2 as it was in LMS 3.2 ? Why after a while after discovery of devices (state is "Known") DFM drops the state of devices to "Learning" and it stucks forever. Restarting of daemon manager works for a short time. It looks like the processing of faults stops a while after discovery is complete.
 
LMS 4.2 is running on Solaris 10, connected to other LMS in DCR Slave configuration.

Cisco Firewall :: ASA 5500 - Learning Mode For New Rule

Mar 29, 2012

Can you set the ASA 5500 series to learn the rule itself? I am talking about putting it into learning mode for first few weeks. I have done this with Zone Alarm software, but not sure this is available in Cisco 5500 series.

Cisco Wireless :: 5598 - New Installation / LED Stuck In Amber Mode

Oct 9, 2011

I am currently supporting an engineer onsite remotely  and have come across a strange problem . I have installed a few controllers but none of them have behaved in this manner. The  model is a WLC  5508-50k9 model wireless controller and software 7.0.98.0, I  have seen as per installation guideline that  amber means th following
 
Distribution ports 1-8 Off: Not present.
#Green: Indicates SFP port is active and link is established.
#Amber: Present with failure
 
This mean that so coherent fault lies as follows on Layer 1&2 . The switch port light does not go green either. We have used both xover and straight but no luck

Cisco AAA/Identity/Nac :: 2960S Switch-port Stuck In Guest Mode?

Mar 18, 2012

I am using 802.1x authentication with multi-domain ports; Phone and PC connected to phone. The phones are Nortel (Avaya) and the PCs are Dell/HP Laptops. All are configured for Certificate authentication and this works well. However we sometimes get some ports stuck in Guest mode. when a non certificated laptop connects to a phone port and fails authentication, the data port is placed in the Guest VLAN. However when the laptop disconnects the port isn't reset and remains in the guest state. When a subsequent good laptop connects and attempts to authenticate the switch ignores this and leaves the data port in the Guest VLAN. he switch is a 2960S with Version 12.2(58)SE2 IOS.
 
The port is configured as follows:
 
!
interface GigabitEthernet1/0/15
description DANS Port
switchport access vlan 1807
switchport mode access
switchport voice vlan 1855
priority-queue out

[code]....

I placed the AAA, dot1x, eap and auth debug on for all events and then connected a good laptop, the only debug message I got were as follows:
  
Mar 19 16:17:01.391 GMT: AUTH-EVENT (Gi1/0/15) dot1x_switch_is_restrictive_vlan_open_auth:Multi-Host with Guest Vlan/Auth Fail Vlan or open aut
Mar 19 16:17:01.653 GMT: AUTH-EVENT (Gi1/0/15) dot1x_switch_is_restrictive_vlan_open_auth:Multi-Host with Guest Vlan/Auth Fail Vlan or open aut
Mar 19 16:17:02.654 GMT: AUTH-EVENT (Gi1/0/15) dot1x_switch_is_restrictive_vlan_open_auth:Multi-Host with Guest Vlan/Auth Fail Vlan or open aut

[code]....
 
I would have expected the auth function to have reacted to the EAP packets sent by the good client when it connected and performed eap authentication but it didn't, all it did was say the ports in Guest mode and left the laptop in this VLAN.

Cisco :: Spanning-tree Every Port Go Into Listening / Learning State

Apr 4, 2012

Ages ago I was shadowing someone making a change on the network. I cannot remember which spanning tree version was running and cannot remember the config of any port either. What I do remember is that every switch port on the 2960 switch went orange and an outage occured, where the ports went into listening / learning mode. I assume that the STP was just the default ieee 802.1D.

Cisco Switching/Routing :: 6500 / ARP Not Learning Properly While Cluster Failover

Feb 20, 2013

I have a 6500 serious switch that one port (portfast enabled) hold a  server .This server has sort of a Cluster configured for high availability .
 
During primary server failure the failover server acquires the cluster IP address (ie virtual IP).
 
Cluster IP 192.168.10.1
 
Primary server =192.168.10.2  Failover server =192.168.10.3
 
when failover happen , i am unable to learn arp. need to reboot the server for arp . After reboot i am getting different mac address(secondary) with cluster IP.
 
query:-normal clustering how mac address generating(means logicaly any mac address will be created or LAN card mac address)?   Is ther any issue with portfast configuration(with out portfast configuration TCN will generate and max age timeout decrease 15 second from 300second) ? 

Note : we checked a scenario same ip address  with two system(ipconflit) and removed arp learned system from network and same thing happen we need to clear the arp manually in L3switch

TEGs80G - Swap Unmanaged Devices With More Expensive Cisco Devices?

Jun 1, 2012

Currently my home network is being switched via TrendNet TEGs80G unmanaged gig switches. I have been using them for about a year now with no issues. As my home network becomes more advanced, I recently just added a Cisco ASA5505, I am thinking about swapping those unmanaged devices, 4 of them, to managed. I was looking at the Cisco SG300-10 for upstairs, and a 16 port variant for my main core. These devices do not support full Cisco IOS cli, but they are manageable with a rich feature set nonetheless. My question is, should I swap the unmanaged devices with the more expensive Cisco devices, or just keep what works and save the money until I really need to spend it. As previously stated, my home LAN works just fine as it is, however my WiFi, NTV550s, server and workstations are all on the same network. Probably not the most secure but it is what it is without VLAN support.

Linksys Wireless Router :: E4200 Can See None Of Devices Attached To Power-line Devices

Aug 15, 2011

I have installed my new E4200 and it works beautifully.  I have several wirelss adapters and a few wired connections through powerline adapters. I also have a second VPN router attached to the 4200.I can see the wireless connected devices with the associated IP addresses.  If I plug a laptop directly into the Cisco, I can of course see it.However,  I can see none of the devices attatched to the powerline devices?  I have a securty cam connected via the powerline and want to know the IP address.  I checked with cisco technical support via chat and they said it is impossible.  I have used 2 previous routers with the same configuration and can see all devices.

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?

Cisco Switching/Routing :: Changing 4510-SUP-6E Redundant Mode To Share-Backplane Mode

Mar 12, 2013

I received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
 
In a redundant Sup-6E setup, the following configuration is supported :
 
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
 
If you invoke shared backplane mode, the following configuration can also be supported:
 
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
 
Here's the command and information about the "shared-backplane" mode :- [URL]
 
Currently, we have 2  SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:

1- One will be used  to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
 
My questions are:

1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?

Wireless Devices Can't Connect To Wired Devices?

Oct 11, 2012

All of a sudden my laptop, android phone and blu ray player (all wireless devices) can't communicate with my wired devices (marantz receiver and samsung tv). Everything still connects to the internet independently but i can't for instance play music from my wireless laptop to my wired marantz receiver. I had no trouble with this last week and didn't change anything (that I'm aware of) I did get Verizon to switch out my router but it didn't solve anything. My wife's computer also cannot connect to wired devices. Lastly, if I connect my laptop with via ethernet cable it sees wired devices fine. I tried shutting off windows firewall but didn't work. I have no other firewall/virus software installed. I can ping to all devices (wired and wireless) from my laptop.

Cisco WAN :: 1751 Router Stuck In ROMmon?

I do not have a cross over cable and have to use xmodem. I set the baud rate to 115200 and I can see everything fine. Using Tera Term when you send the file via xmodem it freezes and closes on packet #3 or about 384 bits. When simply clicking the send file button you get the error-

Cisco WAN :: Branch 867vae-k9 Atm Output Stuck

Mar 14, 2013

we installed two weeks ago a 867VAE-K9 as a border router for a medical practice.It's got two vlan interfaces for inter-vlan routing, only one Gi interface up in trunk mode to the core switch and the ATM for ADSL2+ connection to the local ISP. A cisco wap is on the secon vlan for the patients. There is a voip pbx on a linux machine that registers 5 trunks to an external provider (only one trunk is used right now, and it works fine).(Almost) everything works fine :-) Sometimes (it can be hours or days) the routing to the internet stops. The meds can still use the LAN accessing everything in it with no lag, and the patients can access the isolated SSID on a Cisco wap on the second vlan. They simply cannot surf the internet.
 
- DNS and local routing is fine
- the router is reachable through the Gi interface
- they can send and receive traffic to and from the 867 vlans' IPs
- the ATM, dialer 0 and virtual access are up, line protocol up
- the dialer has got the IP address negotiated from the ISP
- default route is negotiated through ipcp
- the controller vdsl 0 is in showtime! state
- from the outside we can ping the PPP peer, but not the IP of dialer 0
 
The only thing is the queue counter of ATM which shows drops and total output drops. Attenuation is fine, noise margin not so well. The point is that outside traffic to the internet is at low levels and the routing almost always stopped when no one was using the internet (i.e. out of office hours). It already happened 7 times in 16 days. The problem obviously is that voice traffic is impaired by the stuck router, and no med there is able to ssh into the router and re-activate the atm 0 with a shut/no shut.
 
It is not necessary to reload. A fast shut/no shut of the atm0 (no wait between the commands) will make it running again.We're activating the smarnet for this router to update dsl fw and ios image, but I thought I could post here before that.[code] As a brutal workaround till the update/fix, I was thinking about monitoring the reachability of some external systems and use snmp from the lan to shutdown/no shutdown the atm (though I don't even know if that would be possible from snmp on this router).
