Cisco Switching/Routing :: 3750-X Stacking Switch By Switch
Nov 18, 2012I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else. What I would like to know is what are the effects of having the master switch itself lose power? Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?

Apr 11, 2012 I followed the 3-switch Redundant stacking diagram and now when I boot up the stack Switch 2 is acutally Member 3 and Switch 3 is Member 2.
We plan on having Port-Channels spanning across Switch 1 - Master and Switch 2 (Member 3) of identical port types. Switch 3 (Member 2) is going to have 2 10GIG port channel created.
Is there going to be a problem renumbering the stack as they physically sit or should I just configure the devices based on thier logical member numbers.
I don't understand why the stack connection is Switch 1 - 1 ----> Switch 2 -1
Switch 2 - 2 ----> Switch 3- 1
Switch 3 - 2 ----> Switch 1 - 2

Cisco Switching/Routing :: How To Monitor 3750 Stacking Port In LMS
May 24, 2012I would like to ask about 3750 stacking and some Cat6 stuff...
1) How do we monitor 3750 stacking port in LMS?
2) Let say if I stack 3 switches, middle switch should be Master. Uplink should be at Top and Bottom. Is best practice?
3) Can we mixed 3750G and 3750X and what is result internal BW - fallback to 32Gps?
4) is there any Qos difference between WS-X6816-10G-2T and WS-X6816-10G-2TXL?
5) is there any Qos difference between MSFC5 PFC4 and MSFC5 PFC4XL?
6) What is main difference between PFC4 and PFC4XL in Sup2T?
7) Pls share more about Central and Distributed Switching in Sup2T and which card support Distributed DFCXL?
Cisco Switching/Routing :: Build Improved Redundancy Into LAN By Stacking Two 3750
May 1, 2012I plan to build improved redundancy in to my LAN by stacking two 3750s and teaming pairs of NICs on my Dell PowerEdge servers, with each cable of the pair going to a different switch.In my mind this provides redundancy for the NICs and the switches. Does this configuration will work, and also what type of teaming is supported, as I was planning to have one NIC active and one standby, but can I run this configuration with both NICs in the team as active with load balancing?

Dec 19, 2012We are going to upgrade our IOS on our WS-C2960G-48TC-L. But before we do that i want to ask whats the best IOS release to choose. Why we want to upgrade is because our switch software now don't support ssh just telnet access
Switch details:
Model: WS-C2960G-48TC-L
SW Version: 12.2(25)SEE2
Image: C2960-LANBASE-M
I was thinking about upgrading the IOS to 12.2(44)SE6 are maybe i should upgrade it to a newer release?
One more thing we have a bunch of stacked 3750 switches, that also need to be upgraded.
Cisco Switching/Routing :: InterVlan Routing With 3750 And 2960 Switches?
Nov 21, 2012I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

Feb 7, 2012I have switch 2960 and router that connect with one interface to that switch. the link is trunk and Router function is inter vlan routing between 4 vlan. This netwrok has only one ip address space that is 10.10.2.0/24 and work without problem. We connect cisco switch 2960 with optic link to another switch that in stack 3750 which configured as trunk link and allowed only 3 vlan between them. In the other side netwrok which consist the switch 3750 we have different subnet ip address that switch working in layer 3 too. the problem is that when I permit vlan 210 in the switch 2960 only layer 2 between this switch and the 3750 in network that consist th ip address 10.10.2.0/24 devices, if I disconnect and then connect pc to network he says that he has ip conflict and in the log he show mac address of router that has vlan 210 subinterface configured with 10.10.2./24 subnet. But how I gibe back vlan 210 from permited vlan in trunk devices start normaly working. If I again put vlan 210 to permit vlan in that trunk devices again said that there are conflict ip address and show mac address vlan 210 router subinterface.

Jul 26, 2012I'm fairly new at trying to create isolated network segments on Cisco switches. What I'm trying to do is have multiple isolated paths that originate from my v Sphere infrastructure travel through a layer 2 link, v LAN, up to a MLS, and ultimately out to to the internet through a firewall. Each sub net might ultimately have a number of hosts on it, but I don't think the make up of those hosts will matter here.
My initial thought was creating v LAN tagged port groups on v Switches on my v Sphere infrastructure. Physical connections will go from my ESXi hosts to the 2900 series Cisco switch connected to trunk ports. Both v LANs would be configured on the switch but not assigned to physical ports. The physical connection to the 3750 would also be a trunk port connection from the 2960. The 3750 would have SVI's created that are attached to VRFs that would control route traffic. This might be totally wrong but from what i've read it seems to be going down the correct path I think.
Two part question, is this the best way to go about designing this network? If so I seem to be really struggling with the SVI/VRF part. Every time I create an SVI all of my hosts on the 10.10.10.x network can ping them, regardless of which v LAN they're on.
I just cannot seem to isolate the 172 network.
Cisco Switching/Routing :: Cross Stack EtherChannel From 3750 To 2960
Mar 25, 2013We have a pair of WS-C3750X-24T-S in a stack and four WS-C2960S-48TS-L in a stack of their own. There is not really anything too fancy configured (no special VLAN configuration/trunks or etc.) but the 3750 do have two ports configured as L3 for routing. We are not trying to use those ports for EtherChannel. These devices are running IOS 12.2(55)SE3 Essentially we are attempting to make an EtherChannel group using port 48 on all four of the 2960's in their stack (four ports). On the 3750 we will configure an EtherChannel group using port 23 and 24 on both switches (four ports). We then connect them up to form a four member EtherChannel.The ports on both ends are configured as mode ON and they are all 1Gb ports. I elected mode on because I understand at least one of the EtherChannel protocols will not work cross stack. What I would like to ask is whether the above configuration is possible or are we hitting some sort of limitation of EtherChannel cross stack, etc..? I cannot find anything to suggest this configration is invalid, but thought I would ask to see if I missed something in the EtherChannel articles.
View 3 Replies View RelatedCisco Switching/Routing :: 2960 / 3750 - Port Disables Every 10 Minutes
Aug 15, 2012I am experiencing the same problem described in this post {URL}. I have seen this happen on different networks, with different equipment attached. It happens on both 2960 and 3750 switches. Basically the connection drops, and we see in the web interface "Port is Disabled". This appears to happen every 10 minutes.
On the CLI, the status shows as connected.
Port Name Status V lan Duplex Speed Type
Fa0/38 connected 1 a-full a-100 10/100BaseTX
I have ran cable diagnostics while the drop out is occurring.
Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ----------------- ----------- -------------------
Fa0/38 100M Pair A 28 +/- 15 meters Pair B Normal
[code]...
During the outage, I see the duplex fluctuate between full and half. The outage occurs for approx 90 seconds. If I fix the duplex and speed at both ends, the outage reduces to around 30 seconds. If I apply spanning-tree port fast the outage reduces further to around 10 seconds. Before I change any configuration on the port, the logs show the interface going down
Aug 16 13:06:51.875: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/38, changed state to down
Aug 16 13:06:52.874: %LINK-3-UPDOWN: Interface FastEthernet0/38, changed state to down
[code]...
However, once I apply the configuration nothing is logged. However we can still see the connection is disappearing for around 10 seconds. I suspect the issue wasn't resolved for the person reporting the problem in the link above, but because the outage is minimized, and not being logged it is going unnoticed.

Cisco Switching/Routing :: Setup VLan To Allow Video Traffic Between 2960 And 3750?
Nov 13, 2011I am trying to setup a network using Cisco 2960 switches with vlans configured. One vlan will handle video coming from four cameras that are connected to another 2960.
We have four cameras feeeding one port each on a 2960, that 2960 in turn feeds one port on the main 2960 which is the video vlan for that site. From the site it goes back to a Cisco 3750 to be sent over to a Sonicwall firewall. If we connect to the 2960 that the camera are connected to we can see the video, but not on the main site 2960.

View 2 Replies View RelatedCisco Switching/Routing :: 2960 / SG 300 Switch - VoIP Setup - Asymmetric Routing Not Working
May 21, 2013I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
