We install a stack of C3750x switches rescently. A HP C7000 blade server uplink to C3750x using etherchannel and 802.1Q.If the trunk includes a RSPAN vlan on it by 802.1q default configuration, the VM on HP blade cannot ping the same vlan server on C3750x.If the trunk is configured by "allow vlan" and exclude the RSPAN vlan, then the connection is ok.

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?
Recently one of our stack switch got failed, Rma raised but we received some different part number.The dobut is like can we stack the below switches.
ws-c3750x-48p-l v02 (old switch)
ws-c3750x-48pf-s v04 (RMA switch)
Can i put in stack the ws-c3750X-12S-E and ws-c3750X-48P-E? considering the follow features:
WS-C3750X-48P-E (Catalyst 3750X 48 Port PoE IP Services)
S375XVK9T-12253S
CAT 3750X IOS UNIVERSAL WITH WEB BASE DEV MGR
WS-C3750X-12S-E (Catalyst 3750X 12 Port GE SFP IP Services)
C3KX-NM-10G
S375XVK9T-12255SE
CAT 3750X IOS UNIVERSAL WITH WEB BASE DEV MGR
Can we use WS-C3750X-12S-S and WS-C3750X-24T-S in a single stack?
View 7 Replies View RelatedHad a Sev 1 issue today. We have a bunch of Nexus 5ks connecting to some HP C7000 Chassis for the use of Virual environments. Engineers build and tear down servers during the day, however today, an engineer configured a virtual machine accidently with its IP address as the default gateway. Each pair of nexus switches has one physical SVI per vlan and a HSRP address for the vlan. Of course this engineer configuring the server IP address as the HSRP address killed the vlan... which lead me onto think... are they are tried and tested techniques to protect this from happening on the switch. Enforcing the ARP/MAC of the HSRP address and not allowing it to change or any other device to change it?
View 2 Replies View RelatedIs there really any reason why you wouldn't use spanning-tree portfast on a trunk port other than a trunk between two switches? We have it enabled on all ports except for the fiber trunk between two non-stacked switches and the trunk ports connected to our Astaro firewall.I'd like to enable it on the ports to the firewall unless that would cause issues.
View 9 Replies View Related we recently aquired a managed services job and have to do a overhaul of the vlan configs and have a whole dozen WC2948G's trunk between a set of ports as well as trunk out a LAG channel setup to non cisco equipment. the deal is the lacp-channel works properly on both ends but no routing of vlans between ports and between the lag trunk are working.
theres alot of settings in the config and im planning on clearing it and starting from scratch but before i do i want to know where my problem lies.

requesting information via SNMP from my two stacked C3750X, running IOS 12.2(55)RE5. The stack is up and running and everything is just fine. There are three PowerSupplies installed with a PowerStack, also running like expectet.My problem ist to get the status-information about the chassis-fans. I couldn't find any information about the OID and the search results only in some non-useful information about the MIBs from Cisco which delivers only three information about installed fans (and fan-containers), so I guess these are the information about the fans included within the powersupply?! The chassis-fans are installed and the LEDs are green for all four fan-mounts, up and running.

We are trying to monitor two stacks of CISCO WS-c3750X running IOS 12.2.(58)SE.
We can get the state of the power supplies, but after a power cycle or reboot of the switches the identifier of ONE of the Power supplies ALWAYS change. The OIDs for the rest of the PS do not vary. The problem happens in the two stacks.
Currently, my Cisco 3750x (2 switches stacking) is having very hight CPU. Below are some of the output :
3750-ANA#sh processes cpu sorted | ex 0.00
CPU utilization for five seconds: 55%/30%; one minute: 55%; five minutes: 55%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process

I am not sure what is using CPU to go up like this. I had tried some troubleshooting guide on Cisco web site like "Troubleshooting high CPU Utilization"

View 5 Replies View RelatedI'm experiencing strange issue with my WS-C3750X-48T-S.
Model number: WS-C3750X-48T-S
System image file is "flash:/c3750e-universalk9-mz.122-55.SE3/c3750e-universalk9-mz.122-55.SE3.bin"
This switch is situated on a remote site and on the 6th of January it was rebooted.
I still do not know the cause, but it might be power outage or smth. We are still checking. After the reboot I've noticed that one port on this cisco switch is in 'notconnect' state, while I'm pretty sure it should be 'connected'.
I've tried to shutdown the port adminstratevly and do the 'no shutdown' but this port remained in 'disable' state.

I want to deploy the C3750X 24-port SFP switch as the core switch in a large Layer 2 switching domain.The switch will need to run:
+/- only 10 large VLANs, 6 VLANs with HSRP
+/- 500 MACs total
+/- 5 OSPF sessions default timers
standard PVST+ (no Rapid PVST+)i need around 27 SFP ports (24 + 4 on network module=28=ok, extra capacity by stacking)
Looking at the switching capacity of the specs (160 Gbps) this is much better than a C6500 with SUP32-GE !Will it be able to handle this or should i look for C6500+SUP32GE or C6500-SUP720 or maybe even C4500 ?
First of all I purchased the switches with part no. WS-C3750X-48P with the following IOS c3750e-universalk9-mz.150-1.SE1 & IOS feature license to work as ipservice.
Symptoms:
1) - When running the switches in stack mode (connecting the booth switch with full-duplex stack) I found the cpu utilization on each switch reached to 34% The Hulc LED Process reaches to 20%
3) - After about 1 hour with no connections to the switch I found the status not changed.
4) - I tried to run each switch in stand-alone mode (without stack cables connected) & monitor the status of the cpu utilization. I found it the same problem exist. Actions taken:
1) - Refereeing to the internet I found a bug ID describing the status of the mentioned symptoms (attached)
2) - I made a down grade for the IOS version to be c3750e-universalk9-mz.122-58.SE2.bin
3) - The mentioned IOS solved the Hulc LED Process (became 1 : 3 % ) & however cpu utilization became 18% with no links or traffic connected to the switches.
4) - I guess that 18 % utilization is too much for a free switch (refer to the show run file) as I did not configure any advanced commands.
Which is the best and advanced IOS for c3750x-48P-E stack switch among below listed IOS.
c3750e-universalk9-mz.122-58.SE2 ?
or
c3750e-universalk9-mz.122-55.SE6..??

View 3 Replies View RelatedI just loaded the web interface IOS on a C3750X. The first thing I noticed was there was basically no web interface. I can look at things, and do default configurations on ports, but it doesn't appear I can configure VLANs or QoS or anything like that.

I have running a Stack with two C3750G-24TS-S1U with the IOS c3750-ipbasek9-mz.122-50.SE3.Now I want put a new C3750X-24T-S in the existing stack. I have read this is possible. I have running a other mixed stack with a C3750G-12S and an C3750E-48TD. Its running fine until I want to make an IOS update. The update was done with the CW LMS 3.1. After the automatic update and restart only the C3750E had an new IOS the C3750G doesn't have any IOS. Do I have the same problem with the mixed Stack C3750G and C3750X?Do I have to upgrade the IOS by copying the different IOS Versions ( c3750-ipbasek9-mz.122-50.SE3 / c3750e-ipbasek9-mz.122-50.SE3) to every switch ?

I would hate to send them the gig switch when there isn't as much usage..Besides if I can get my CFO on this switch he might authorize me to replace the rest...

View 3 Replies View RelatedAny issues are reported while configuring power stack ? We did several times with 12.2.58SE1 and SE2, sometimes the power stack is created automatically, sometimes needs to be configured manually. Looks like the behavior is not the same. Maybe it depends on the number/type of switches and number/type of power supplies.

We have a new backbone in our LAN with two C3750X-24S 15.0(1)SE3. Since we change the model of our equipment we can't update NTP on this two switches.We try to update NTP with two firewall Juniper SSG-140 in version 6.3.0r12.0. The two switchs never arive to associate with firewall (we try with the comme ntp server and ntp peer)
So we configure ntp server on our distribution servers switchs (one 4900 12.2(54)SG and one stack of 3750G and 3750E 12.2(50)SE5). They have no problem to update NTP on the firewal.So we change our configuration ntp server on the backbone and we try to update it with the distributions servers switchs. With the command ntp server it doesn't work. With the commande ntp peer it works but not everytime. The core switchs are in "synchronized" state then "unsynchronized" then "synchronized" etc...When they are in "unsynchronized" state there is "x falseticker" raison behind the IP of the ntp peer.
Is it an IOS version problem on our core switch?
