Jan 28, 2012According to the following Cisco webpage, cross-stack 10-Gigabit EtherChannel is possible on the 3750 with up to two 10-Gigabit modules, using LACP: url...However, the webpage doesn't confirm if this functionality is restricted to a particular 3750 model, such as 3750E, or if it applies to all models. It also doesn't specify any particular IOS feature set. I've tried Cisco Software Advisor but it doesn't list this feature on either the 3750E or 3750-X. This is possible on the 2960-S switches (i.e. cross-stack 10gig EtherChannel)?

Oct 26, 2011Does 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. We tried to try different scenarios, and it looks like it does not matter what cable end we use. We do not have any external power supply, only interconnecting C3750Xs.

Dec 11, 2011At a customer i've tried to add a new 3750 switch til a running stack.I used the following proccess:
1. connect stack cables to the new switch
2. bootup new switch.
Normally the new switch will become a member of the stack, but here, the switch says its the stack master. I can see that the stack port from the old switches connecting the new is up.The only way i could make it work was to provisioning the new switch as switch nr x, save, power off and then connect it and boot it up.The IOS i the same on all switches.
Cisco Switching/Routing :: 3750E-24PD-S Stack Member Fan Failed Syslog Message
Aug 6, 2012I have a pair of 3750E-24PD-S stacked together, it seems after stacked together the stacked switch always flood the console screen with these messages which are not true: [code] Switch-2 is the stack member, Switch-1 is the stack master. The RPS fan failed refers to RPS2300 or the internal power supply of 3750E? Even when I turned on the RPS2300 the stacked switch still display the messages. Also I have two RPS2300 serving stack master and stack member respectively both RPS2300 were switched off why the messages only refer to Switch-2 and not Switch-1? [code]

Cisco Switching/Routing :: 2960G Configuring Ether-channel On Stack-wise Stack
Sep 24, 2012A site that i am responsible for has the following equipment installed:
2 x 3750G Switches configured as a stack using Stackwise - Collapsed Core/Distribution Layer
5 x 2960G Switches as Access Layer switches
WAN connections into the Core/Distribution Layer are all Gigabit Ethernet over Fibre.This is a dedicated CCTV Network with 50 Cameras all streaming video into the Core (decoders connected to access switches)Each 2960G has 2 links to the Core/Distribution 3750G Switches, 1 to each switch - Gigabit.I'm running rapid-pvst on all switches, so spanning tree is blocking one of the ports and effectively halving the 2 gig bandwidth. Next year our customer is going to add in a further 50 - 60 cameras.After monitoring the current loading on the ports in use, we have suggested to the customer that the 2 connections to each should be Ether-channeled together. [code]
First interface takes commands no problem, keep getting the message that etherchannel cannot be configured across different switches in a stack when i try to put the second interface commands on.
Cisco Switching/Routing :: 3750E / Applying ACLs When Routing Between SVI And Routed Interface?
Mar 12, 2013Quick question here. Using 3750E series switches with multiple VLANS configured. These switches serve as our 'core'. I have SVIs configured for the different VLANs and add inbound ACLs in each of the SVIs to control traffic between VLANS. This switch also terminates a P2P Ethernet link which connects to our Colo facility. The port used for this is configured as an L3 port. I noticed today that I was able to send traffic across this L3 link that I thought should have been blocked by an ACL I had in place but it wasn't. So the traffic flowed from a port in say VLAN 20 across this L3 link (assigned with an IP address). Would this traffic flow not cause traffic to be checked against an ACL applied in the inbound direction on the SVI of VLAN 20 (int vlan 20)? Traffic does get checked when routing between SVIs. Why would it not get checked when routing between SVI and L3 interface?

Cisco Switching/Routing :: 3750E RACL Slow To Load
Apr 16, 2012I am seeing on my 3750E series switches (WS-C3750E-48TD). I have multiple VLANs configured on here, one which is used as a 'workstation' VLAN. I have an inbound ACL applied to the VLAN interface *(int vlan 50 to be exact). This list is admittedly long at roughly 6000 ACE's. Now I just recently installed these switches as they replaced some 4507R switches which we moved to our new centralized DC. Here is the issue I am having. This same ACL was applied to the same VLAN interface on the 4507s when they were doing the work of the 3750s. What I used to be able to do was actually edit the ACL by removing it with no ip access-list extended WS-In and then followed up by the ip access-list extended WS-In ......and the lines I wanted in the ACL. I know I could use the line numbers to edit the ACL but this worked OK for me. When I would do this on the 4507R, the ACL was still applied to the interface but traffic never seemed affected by the removal and re-adding of the ACL. I did this by copying and pasting the ACL into a terminal window. It seemed as though on the 4507 the ACL was not compiled until the entire thing was in loaded in and therefore traffic was not processed by the ACL until the load was done

View 4 Replies View RelatedCisco Switching/Routing :: 3750E / Traffic Prioritization Involving VLANs?
May 30, 2012I have a device which will be sending voice and data packets and is able to mark the packets with DSCP values. Voice, 18 and Data 42.If this was a straight through network, I'd be clear on how to handle this, but.....I will be putting this traffic into a VLAN to isolate it from some other traffic on the network. What is the best way to prioritize this traffic inside the VLAN? Will the Cisco switch look at and respect the DSCP values inside the VLAN and prioritize accordingly inside the VLAN? Or, do I need to do some sort of DSCP to 802.1p mapping? Another option I would be fine with would be mapping the DSCP values for voice and data to two different VLANs and then giving the voice VLAN priority over the data VLAN .... I'm using 3750E switches.

Nov 7, 20129x3750E stacked switch (WS-C3750E-48PD-SF0) (15.0(1)SE2
C3750E-UNIVERSALK9-M)
2x10Gbe uplinks from EMC NAS
At a basic level, we have found that the 10Gbe uplinks have slow read performance with or without a port-channel configured (2-3 minutes for a 700MB file to desktop from the NAS) We switched back to testing a 1Gbe and the read speed is normal. Another anomaly is Win7 / 2008 machines read speed is fine from the NAS while the 10Gbe uplinks are in production?!
Write speed is great on 10Gbe. Only read speed is affected!! the switch is not reporting anything abnormal. We looked at SMB/SMB2 as another possible cause...
mls qos is enabled on the switch but not sure if this is affecting performance.
Is the ANY config that I need to carry out on the interfaces to get the read speed working as it should for both Win7 and WinXP. (MTU is 1500 throughout the enterprise, NAS included).

Switch 3750E has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules. Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ???? the other SFP slot is disabled automatically?
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module is considered, this will be connected to SW3750E by means of SFP-H10GB-CU5M.
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.
