It is said that the switching fabric of WS-C3750X-24T-E is 160Gbps.Could any body tell me what is switching fabric, any relevance or difference from forwarding rate?,Is there any document to know how will the switch reach the 160Gbps full switching fabric performance?
View 5 RepliesRecently 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 5 Replies View RelatedI am looking at the utilization on a Catalyst 3560-E. I am running a test with eight 1 GIGE links RXing at 95 % utilization. All of the traffic is going to a TenGigE port. The device on the TenGigE port is echoing back all of the traffic received, so the 1 GIG links are TXing at 95% as well.When I do a "show controllers utilization", the port utilization numbers are correct, but the fabric utilization is higher than I would expect. The fabric should be 128 gigbits / second in this switch, and there is 7.6 gigabits TX/RX to the ten gig port. The fabric utilization is at 49%. I would expect 7.6 / 128 = 5.9% or possible double that. [code]

Need clarification on the VPC with 5k and 2248 Fabric Extenders. My question is can each fabric extender uplink to two different 5ks, and at the same time, have servers connected to two both fabric extenders with a VPC.So basically, the server NIC will team with two different fabric extenders, and each fabric extender will connect to two different 5k's.

Cisco Nexus 2232 can only connect to End Hosts and not to a switch. Is there a New Feature added in Nexus 2232, which enables it to connect to a Switch like HP Flex Fabric ?
View 1 Replies View RelatedHow to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.

View 2 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 1 Replies View RelatedIn my MDF I have a 4stack of the WS-3750-48P switches. Is it possible to replace one with a C3750X48PF-S with out causing any issues? Or would it be better to just have 3 stacked and trunk this one to the core 4506. Keeping in mind I bought this one to expand the port number for one of our remote offices.. 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... He is reticent to believe it makes really all that much of a difference.

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?

I have a problem with dscp preservation on a WS-C3750X-48 catalyst; in my little diagram, his name will be SW2, so I have this:SW1 <-> SW2 <-> RT1. some phone connected to SW1 mark with dscp EF (46) the voice traffic.The "mls qos" was enabled on SW1 and SWt. The interlink switch ports has the "mls qos trust dscp" option, the phone port and the router port also.And the problem is I can see the dscp marking on the SW2 when I span the voice vlan on this switch but the dscp was removed ( DSCP set to 0) on the router port ( span on the router port for look )If I made also a packet capture on the router RT1, I see the DSCP was effectively reset to zero.If I disable the "mls qos" on SW2, of course all is fine and the dscp was preserved and forwarded to the router.

View 2 Replies View RelatedDoes the color strips on C3750X stack power cables mean anything, I mean the green and yellow ones. On all Cisco pictures the green one seems to be plugged in the upper ports. I asked local Cisco representative, but he seems not to be sure.
