I have a Cisco3800 with IOS Version 12.3(14)T2 and I have an HWIC-1GE-SFP module inserted on it.
I need to know if there is a command to verify optical power level in this module inserted in the Cisco 3800 router?
Something similar to the following command that I can execute in an Cisco ASR9K:
show controllers Te0/0/0/1 phy | i Rx
I have an C4900M with twingig converter and SFP GLC-LX-SMD in. So the SFP supports DOM function. It is running on 12.2(53)SG2.
I would to the see the optical power level of the SFP, but it does not recognize 'show interface transceiver' command as showed in 4500 software guide.
We are using WiSM WLCs and WCS to control a variety of 1131,1142 and 1252 APs utilising AP groups.
I've noticed on WCS that the power of certain APs is at a low setting, even though the APs surrounding them are also at a low setting. This is causing some gaps to appear on the heatmaps. I was under the impression that the WLCs would regulate the AP power to compensate for any gaps. Currently the global TX power level assignment method algorithm is set to automatic every 600 sec.
Now, obviously I could change this to fixed (not ideal as I may not want all my APs to run at max power all the time) or to on demand (also not ideal due to the increased admin).
Is there a way I can verify that the automatic power levels are adjusting as they should? Why are there gaps appearing in my heatmaps?
*NB It's not just the gaps on the heatmaps, I'm getting reports of dropping wireless signals from users hence me looking at the heatmaps and they just happen to correspond.
WLC version 6.0.199.4
WCS version 7.0.172.0
I have a deployment of AIR-CAP35021 APs. They are in 2 buildings with multiple floors. They are installed in a row down the hallways. I want to increase the power levels by using the controller and not configuring the APs individually. I have set the TPC value to -50 but I still do not reach the outer walls of the floors in some areas. I need to know what to set the Max Power Level Assignment or Min Power Level Assignment to to get the APs to power up some more. If the MAX value is 30 and the default is 30 then how to adjust that value?

We inserted a new module with 48 rj45 ports in a 4500 with just one supervisor module. We have two 4500, and we tried the new model in the other 4500 and it´s working properly and giving a OK status. Furthermore, the module´s LED status is green. We saw that there are 8 ports (from 17 to 24) that are in faulty state, so probably this is the cause for the faulty state for the module.
We tried already a Hw reset, replace/insert again the module...
We are almost sure that it can be a Hw failure. We are getting the following results different commands:

I have a ONT with a built in router but I need to install a separate router onto our network by connecting the router to the ONT. I need the extra router so that I could use some 3rd party hardware which can only be configured in D-link and Tp-link brand routers. I do not want to change the ONT system to the standard modem router system because the ONT also supports a system of internet phones. I'm curious if this is possible at all because a repair tech. told me that you could use the router as a transformer but so far it is not working. I'm really unfaimilar with the ONT configuration so I don't know if this plan can actually work . So far the router can not recieve a WAN connection and therefore can not obtain a Ip address.

I was positively surprised to find the optical transmit/receive values using the show fiber-ports optical-transceiver detailed command on a SG300-10.
Now I'm wondering if there is also a SNMP-MIB to query these values? I've already tried the CISCO-ENTITY-SENSOR-MIB used by the larger devices running Cisco IOS, but this didn't work.
I have two SG300-20 Switches and buy two MGBLX1 Modules for the Switches.
I plugedin the Modules but the Modules didn`t work and in the WebConsole i can´t see the Modules.
Is there any configuration to enable the SFP Modules? or is it a problem from my Switches
We're installing ASR1000 series (ASR1001 and ASR1006) routers on a new WAN and have a requirement to enrypt the traffic between the EIGRP neighbors. Each ASR will be connected to the MOE with a gig interface and we will be using L3 on the interfaces with EIGRP as the routing protocol. We have advipservices-k9 IOS-XE
The ASR1006 is our datacenter WAN router and all remote sites have the ASR1001s. The ASR1006 WAN interface will be configured with L3 subinterfaces, one to each remote location, using a /30 mask.
What is the best method to encrypt the traffic between the ASR1006 WAN interface and the remote ASR1001 WAN interface?
I'm working on setting up a site-to-site VPN connection that requires us to NAT an internal address. Typically, this would be no big deal, but for some reason, it's not working for us. The remote site is reporting that they are seeing the original IP address and not the mapped address coming across. I've monitored the connection and base on our ASA logs, I too see the un-mapped address.
Is there a quick and easy way of verifying that NAT is working? Logs, etc.?
Unfortunately I don't currently have the remote side's configuration, as they are an external business, but I can provide ours: [code]
Based on the above, it sounds as if our configs aren't jibing, which I would think could be caused by the NAT configuration not working, right? I mean if the VPN applicance on the remote end is expecting a NAT-ed address of 12.131.67.247 and they are receiving 12.10.127.108, that could cause this issue, couldn't it?
Is there a device, which is able to produce a time delay on fiber optical link? I mean for example if one would like to reduce the power level of an optical signal, he could use simple air-gap optical attenuator on optical link. However, has somebody seen a device, which is able to introduce a time delay on optical link?

View 1 Replies View RelatedI used the wlc 5508 GUI to enable multicast in the CONTROLLER section, AP Multicast mode "Multicast" with a group address 239.1.1.1. Also in the "Multicast" section enabled Global Multicast Mode and IGMP Snooping.
My wired network is using a bsr and pim sparse-mode all around. My wlc is connected to a core 6513 L3 switch and on a neighbor L3 switch I can see a shared tree mroute entry and a source based entry for the wlc multicast group I created,
sh ip mroute

In the monitor multicast section of the gui I can see some Layer2 MGID entries and one in the Layer3 MGID section but not for the 239.1.1.1 address.How do I verify my multicast over wireless setup is working correctly?
