I have 5 to 6 878 routers and in all these routers the ATM interface is stuck up with initializing mode. This is the IOS running on it c870- advipservicesk9-mz. 124-15.T9.bin
View 1 RepliesWe did an upgrade from NX-OS 5.1.5 to 5.2.4 and found all M1 line card interfaces were stuck in initializing state for long time.'show module' status says ok. And we cannot execute shut/no shut command under the interface. N7K-M108X2-12L & N7K-M148GT-11 are the two M series cards. Only option was to downgrade back for the time being.

I have a couple of 3560 switches running c3560-advipservicesk9-mz.122-44 and they are randomly experiencing the following:
- The switch locks up with no preceding error message in the log (I am forwarding syslog to Splunk).
- Upon reboot, the switch goes through the normal startup sequence with no error messages, then for some reason reloads the flash and starts all over again. (refer to doc)
This could happen after days or weeks. Sometimes they will go through two of these reloads on boot and be fine for awhile, and other times they will be stuck in the loop infinitely. I am using this same image with all of our 3560s, but am only having this issue with two of them.
Is the ADSL line interface on Cisco 877W not initialising a known issue? This interface on my router has been in this state for more than one month, with the rest of the router seemingly operational. The interface was connected directly to my ADSL broadband and worked well for two years. But then, about a month ago, the interface went down. I saw the exact moment this happened recorded as a syslog message. The only information was that the interface status had changed to down.
Initially I thought this was a matter of reload the router and all will be well. Did not happen. Then I thought my broadband connection was to blame. However, this option was quickly ruled out. So I went on to exhaust all troubleshooting options, including reflashing the router with the saved image and totally changing the configuration. Still no change. I have had to go back to my old BT home hub for internet access. In terms of speed this actually works a lot better than the Cisco router. But I would still rather have the router connected to my broadband line. What can I do to bring the ADSL interface back to life?
We have cisco 7600 Router with 76-ES+XT-4TG3C Module connected. The Module is getting detected after upgrading the Router with SRD5 IOS.Below are the testing which we have done on the Router but we are facing the issue while configuring the Transport mode LAN and Transport Mode WAN:Brief about this is:- 2 Cisco 7606-s Router with Module 76-ES+XT-4TG3C each.- two ports on 7606-s Ten2/1 & Ten2/2 are configured as a Transport mode WAN while Ten2/3 & Ten2/4 are configured as Transport mode LAN.- We connect Fiber Cable from LAN Port to MUX and from MUX to 2nd LAN Port of the same Router. Same thing we tested by using the WAN Port-MUX-WAN Port connection.- Now on MUX end LAN port, connected Single and Multi mode fiber and on 7606 end 2/4 port which is configured as transport mode LAN, using Multimode SFP module -> XFP-10G-MM-SR, port did not came up then replaced 2/4 port with single mode SFP ->XFP-10GLR-OC192SR port came up. this is testing for LAN.- For WAN testing on MUX end used WAN port and on 7606 end checked with single mode and multimode fiber and with single XFP-10GLR-OC192SR / mulimode XFP-10G-MM-SR SFP, port did not come up.Wanted to know 1) If we have to go for Transport Mode LAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.2) If we have to go for Transport Mode WAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.Anything else is required while configuring the Transport Mode WAN as this is for Packet-Over_SONET/SDH? 3) MUX Side change is required while connecting both of this Modes on Cisco 7600 Router.4) Is hardware of the Router is giving any issue? Though we tested by connecting Back to Back LAN Port as well as Back to Back WAN Port. In both the situation the Ports are coming UP.
View 1 Replies View RelatedI have cisco router 887VA.Question is when i connect that WAN port ( eth0) with any switch or laptop/pc i do not see the port in up state. What can be the reason.I have done "no shutdown " on interface level and there is no configuration on interface except the IP address , but it show " up down "state even the port is connected to some device. ( Is the port is faulty or some other reason).As per my concept it should show up state when we connect to some device ( Like router / switch / laptop).

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
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

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

[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.
On my Switch (3750), i have a host connected. Checked the interface status and it shows as "connected". However, when i tried checking the MAC connected to that interface, its not showingI have my Switch (3750) connected to a Router (3845). On the Switch, i have a printer connected in an interface.

I recently bought a Cisco E2500 for work, and after setting the router to Bridge Mode, I am unable to access the router web interface. I tried both the old IP address (192.168.1.1) and the IP address that I entered when I was configuring Bridge mode, but I couldn't get either to work. I have always tried resetting the switch to factory defaults and trying again to make sure I didn't type anything wrong, but to no avail. The wireless and everything works as it should, I just can't get back into the router to change any of my settings.

View 2 Replies View RelatedUsing Cisco 1811W with IOS 15.1(4)M5. FE0 and FE1 are connected to the internet via Billion ADSL2+ modems operating in bridged mode. Both lines are similar so I'll only discuss FE0 from this point on.Local subnet is 192.168.128.0/24 with router on 192.168.128.1 as default gateway. Modem on FE0 has static LAN IP of 192.168.128.2 and when plugged into the switch on the LAN side, the web interface can be accessed at that IP address. Unplug the modem from the switch and plug it into FE0 and it now works as desired providing access from the router to the internet but the web interface is no longer accessable at 192.168.128.2
I tried adding a static route "ip route 192.168.128.2 255.255.255.255 FastEthernet 0" and also "ip route 192.168.128.2 255.255.255.255 Dialer 1" Neither worked and presumably it isn't that straight forward. Possibly NAT or other routing configuration required.Although there isn't much to configure when in bridged mode, I mostly want this setup so I can look at the ADSL connection status and for the modem to write messages to syslog (works when plugged into switch on LAN side), or SNMP access.
