I'm having a problem at the moment getting a Cisco switch (2960G) to work properly with a Dell blade enclosure. The config that we have on the switchports is;description Bladeswitchport access vlan 120 speed 100duplex fullndhowever, with this configured, it's throwing up a lot of CRC errors. I've taken the last two lines out, and there are less CRC errors but the connection starts running really slow.Are there any further steps that I would need to take to fully troubleshoot the issue, or is there a simple config change that could be made to resolve it?
I'm trying to get the VFC up in B22-FEX blade in Dell which is connecting to Nexus 5596UP.
The message I get is
# sh int vfc1033 vfc1033 is down (Error Disabled - VLAN L2 down on Eth interface) Bound interface is port-channel3 Hardware is Ethernet Port WWN is 24:08:00:2a:6a:0d:db:3f Admin port mode is F, trunk mode is on
I have used all the ports on my 24 port 2960G and need to extend it with another 2960G. These switches do not have trunk ports so what is the best way to stack them and have all 5 vlans on both switches.Can I just use a port Channel trunk etherchannel ?
i am trying to config my new WAP4410N and a dialog asks me for the PIN as an 8 digit number. none of these have 8 digits.the dialog only accepts 8 numbers. no letters.
I have CAT-5e cabling running from ceiling to floor and need to enclose this as it's quite an eye-sore. I am looking for a 10' x 4" x 4" vertical enclosure but cannot seem to find any unit that is >84".
Since my PC died I have a few internal HDDs I would like to use in enclosures, what brands will work, or will most work if setup correctly ? Anything similar to work on a E4200 v1?
I would like to know if it is feasible to put those Aironet AP with internet antenna like AP1142 / AP1042 in a enclosure box (Like IP66 grade) box. Will those enclosure box absorb the Radio signal from the AP? or the Radio signal can still survive after passing the box but the Signal Strength be degraded only?
I have Linksys E3000 Router and it is connected to 7 Devices at this moment via DHCP. I have got New NAS Enclousre (8th Device) which has got Lan port . I have connected Box to One free Port on E3000 Router. I see DHCP Reservation from 192.168.0.1 assging one IP to My NAS Enclosure Box i.e 192.168.0.13 But when i ping that box . It's not pingable. When i try to browse that NAS Enclosure's setup web page - it's not opening. I can access that box setup page if i connect direct 1:1 Lan cable over private network (169.254.XXX). It means web server is runing on box. I am clueless. E3000 is assigning IP to NAS Enclosure but can't Browse or Ping. I tried to Assign Manual IP address to NAS enclusure and reconnect to router. Still I can't ping or browse.
#arp -a show that box has IP. (Output from MAC os) . ? (192.168.0.13) at (incomplete) on en0 ifscope [ethernet] Ping test from Router Page.

I just bought an E4200 hoping to plug my external hard drive in. Unfortunately, the drive isn't even showing up as connected. I'm using an Icy Box enclosure around a toshiba laptop drive right now.
I have a question regarding WISM2 DP and licensing.
Suppose i have a WISM2 with 7.0, 500AP license today and i activate WISM2-DP by upgrading to 7.2,Do i get 500 AP capacity for free (total 1000AP) or do i get 250APs on each WISM2-blade ?
If i get 500APs for free, why is Cisco selling an expensive licensed 1000 AP WISM2 ? I better buy a single-plane 500AP-WISM2 and upgrade it myself then...50% profit.
Is this the same for a WISM2-300 (supporting 300 APs) ?When i activate WISM2-DP here, do i get an extra 300 AP or an extra 500 APs ? Or 150AP on each blade ?
We are trying to configure Etherchannel between four ports of cisco 3750 stack(2ports from one switch of stack and two ports from another switch of same stack). We are facing issues with this setup. The ports in WS-CBS3012 are going to err disable mode.
Is there any limitations associated with such a cross-stack etherchannel configuration. Any particular sequence of configuration involved.

If i replace a card of the same type in the same slot will I lose the configuration for that card or does it live in the backplane of the device?Is there any special command I need to run to replace the card or can i shutdown the 4507r-e and just swap out the blade?
We have 12 Catalyst Blade Switches 3020 for HP running IOS Version 12.2(55)SE. In the configuration of these switches I see the statement shown below.
no spanning-tree vlan 34,45-55,70,600,643,840,843-850
The 12 blade switches are configured as VTP clients and running VTP V2. I did not configure the statement shown above. It appered by itself. And even if I delete it, it will reapper. (The blade switches are interconnected to two 6509s. The two 6509s are the STP root and VTP bridges. I configure Vlans and STP on the 6509s).
why the statement above appers on the blade switches 3020s?
I mean I use other Cisco switches such as 3750s and 3560s and I have never seen the statement above appear by itself.
Im having problems changing a connection between a Cisco3560 and Cisco IBM Blade switch 3012 actually the configuration is access in Cisco 3560 and trunk int Cisco 3012 when i change the connection to trunk i lose conecctivity to the servers connected in the 3012, i have changed the access from vlan 1 to the respective vlan in the access port of the servers
Looking at the specs for WS-X6704-10GE, it shows the port buffers at 16M per port. This doesn't seem like very much for a 10G port. Is this upgradable or related to how much RAM is in the blade?
it seams, that the mounting blade for the 1142 access point and the 2602 access point are identical.
We have ordered the new 2602 with internal antennas for deploying WLAN in a new building, but I never hold this accesspoint in my hands. We have a few mounting blades in spare from the 1142 accesspoint. The question is, can I prepare the mounting of the 2602 access point with the 1142 mounting blade?
we have 2 WS-X6516-GE-TX, WS-X6516A-GBIC, and a WS-X6748-GE-TX with a WS-F6700-CFC daughtercard
our sup is a WS-SUP720-3B
we are experiencing packet loss for everything connected in the WS-X6748-GE-TX blade, right now we dont have any production device in that blade due to the packet loss we are experiencing.
this switch was running hybrid before it is now running native ios, however I can't recall if we didn't have that packet loss before. do i need to update a firmware of the card or daughtercard (if this is possible, can't say i've done it before).
i have one of my switch modules that shows PwrDown when i issue the command show mod.

i tried disabling the diagnostic monitor for the module, did a power enable module command and then reset it but it still fails. this is the third blade that i am replacing in a few weeks and i still get the same error. i am persuded that it is not a hardware since it is the third blade in a matter of weeks. after the module reset, i receive this error % module 3 is operationally off (FRU-power failed)
could an ios upgrade solve this issue? are there any ios related bugs?
I have a LAP-1142 connected to one of our PoE blade in our 4506 switch, it used to work fine with the following power consumption:
Interface Admin Oper Power(Watts) Device Class From PS To Device --------- ------ ---------- ---------- ---------- ------------------- ----- Gi4/3 auto on 21.5 20.0 AIR-AP1252AG-A-K9 3
However, we had power issue on Apr 28, so it failed and we saw from the log below:

situation: LMS 3.2 Cat6509 w. 4 port 10 GE module connected with trunk to HP BladeSystem c7000 Enclosure with HP Virtual Connect Flex-10 10Gb Ethernet Module with #20 of ESX servers, Citrix
UT settings: "config trunk for end host disc. = enable on this trunk." No show for connected MAC's of the server and end hosts (Citrix sessions).
Note: this works well for a ESX based DL380 server connected with 1GB trunk to a C3750. Why is this not working for this Cat6509 configuration ? Is the 10 GE port supported in Campus manager?
- Incoming frames on three of a blade's four switchports are being put into VLAN 1 even though the ports are either in other access VLANs, or are configured as trunks with different VLAN IDs being tagged by the server. - When the ports go down the access VLAN is removed from the port.

I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
What is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).

I received 3 GESM cisco blade switches for a HP Blade system. I do not have the chassis. I need to sanitize these blade switches but I have never worked with these. I don't see any removable flash. Where is the config stored?
I have a Cisco Catalyst 4507R+E (with Sup7-E) and two blades; one WS-X4748-RJ45V+E and one WS-X4648-RJ45-E.
When I connect a device to a port on the WS-X4748-RJ45V+E blade the port will not come up, show interface shows the status as "notconnect". When I connect the same device to the WS-X4648-RJ45-E blade the interface comes up.
The WS-X4748-RJ45V+E blade seems to have initialised okay, it appears in the output of "show module" as OK.
I get exactly the same effect on a second, identically configured Catalyst 4507R+E.
The software version is IOS XE 3.1.0SG, which according to the release notes supports the WS-X4748-RJ45V+E blade
We have a switch in our IT office, Cisco 2960G. It plugs into the wall and goes to the server room and connects somewhere. This weekend we redid almost the whole server room and now this switch can connect to the rest of the network. The uplink has a link light but can get anything.
I have rebooted the switch, used scanning on our other switches to try and find the MAC of the switch but for the life of me I cant see it. Is there a command I can run from the command line of the switch to see where its pointing?
I am trying to configure SNMPv3 on a 2960G (12.2.(55))
snmp-server view v3view interfaces included snmp-server view v3view internet included snmp-server view v3view chassis included snmp-server view v3view system included snmp-server group v3group v3 priv read v3viewwrite v3view notify v3view snmp-s user v3user v3group v3 auth md5 v3secret priv aes 128 v3secret
Interestingly enough when I 'sh conf | i snmp' the user command isnt there, however it shows it under 'sh snmp user'. Using Solarwinds Eng Toolset to attempt to just pull interfaces and it keeps kicking back with creds failing.
I try to connect a cisco blade switch 3020 to Nexus 2232 with etherchannel, but when I connect the second link a obtain flapping on vlans. [code] why the vlans are flapping ? it's something wrong on the config ? [code]
I have 6 of these WS-CBS3012-IBM modules that need to be configured but I cannot access the USB console port. I was told I could just get any DB9- to- USB cable and that would work. I did buy a DB9-to-USB cable and it did not work. I looked up the installation guide for this module and it just said the console cable is DB9-to-USB but with no part number.
