Is there an association between fiber type, wavelength and distance? I mean are there single-mode fiber cables, which are more suited for 1550nm wavelength and have poor performance when wavelength is for example 1310nm? Are there fiber cables which support only some narrow wavelength range? In addition, how is such behavior called in physics?
View 1 Repliesfind out which types of fiber optic that i can connect to three types of switches. the setup that i have that there are:8 access switches (WS-C2960S-24TS-S), in each one there is two SFP connections.2 aggregate switches WS-C3750X-24T-S, in each one there is four SFP connections.and one core switches that has SFP card WS-X4624-SFP-E? Note that the fiber optic that we have coming from filed are multimode.

View 1 Replies View RelatedWhats the difference between a transform set and a security association? I understand that in the transform set you have to state AH or ESP, but why do you also have to choose a HMAC and an ecryption algorithm? Didnt we just configure that with isakmp? Also what is the point in selecting an encryption algorithm in isakmp if were using AH?
View 3 Replies View RelatedWe have a 5508 WLC with a few WAP's (1131's and 1242's). Our wireless clients use certificate base authentication against our AD (i.e. both computer cert and user cert are required). However, from time to time I see clients being associated but not authenticated as reported by the WLC. Could it be possible, as some literatures indicate that a client can only be "associated" after it's successfully authenticated? Perhaps I'm not quite clear about the concept.

I am running WLC 5508 and WCS version 7.0.98. We are noticing with some of our handheld devices that have Sychip Wireless cards that they constantly have issues communicating. The error I see on the WCS side is shown below:
Client '00:0b:6c:2f:d0:32 (0.0.0.0)' failed to associate with interface '802.11b/g' of AP 'HO-BRSales'. The reason code is '0(null)'.
-WLC 2504
-AP1602
-SW 7.4.100.0
We have 22 x AP1602.5 of them show up in the WLC with Controller Association Latency of around 1 minute and 10 seconds.The other 17 all have latency around 10 seconds.
1. What are possibile causes for high value of association latency?
2. Could high-value association latency be an indication of badly working wifi for data traffic?

It is a Customer requirement to send 802.11 client association/disassociation logs to the Syslog server in a Unified Wireless system. (AIR-CT5508 + LAP1142) [code] Unfortunately I didn't find such logs even in Msg Log with the severity level set to debugging.I was able to do client assoc/disassoc logging with SNMP trap + trap receiver software, BUT is there any way to do this with Syslog?
View 1 Replies View RelatedI'm using aironet 1210, 1130, 1100, 1040 autonomous mode, in a University campus network with thousands of daily user.We're using RADIUS authentication and AES/WPA2.In the past, there were some major issues with traffic (broadcast / multicast) in the wireless networks, that would spread all around the campus causing excessive processing at the access-points.To solve the problem we decided to implement access list at the radio interface to drop all the unwanted traffic.

I'm pretty sure this is caused by the ACL (I've tested removing the ACL and the issue never occurred) but I can't just get ride of it.
Any alternative way to drop broadcasts?
I'm trying to do some basic troubleshooting on our WiSMS. Some clients on a working network are unable to connect in the afternoons, debugging the client on the wism shows this message:

I have been noticing in my trap logs that there are an excessive amount of Client Association/Authentication Failures. I cannot figure out why. I have a Cisco 5508 WLC with 81 AP's (1131ag, 1142abgn, 1262N) models. The wireless devices are on a Windows Domain and use 802.1x EAP authentication, authenticating the user and computer info with a RADIUS Server. I look at the logs and all it can tell me is Reason:Unspecified ReasonCode:1. I read that the Reason Code is due to "Client associated but no longer authorized" but to be honest I am not sure what that means.

Our house is located up a hill and a long way (1,400ft) from the main road and we always have problems with the signal dropping on our cable internet connection. According to the line tech's that have been to our house the problem lies with the 20+ year old cable that is being used to get the cable signal from the road box to the house
I am wanting to replace that cable but from what i have read so far is that cat 5/6 cannot go the distance i require
I have looked into going with a long range wi-fi but there is no direct line of site from the road to the house and there are a million tree's in between us and the road so its not really practical .we are not needing any major amount of speed, just enough to do surfing, streaming, and the kids like to do multiplayer gaming. 7-10mbps would be great for us, before we started having problems with the cable we were only getting 4-5mbps and that was enough for what we needed
