Cisco Switching/Routing :: Switch 3750G Stack
Jun 17, 2012have one 3750G stack with 4 switches and this stack is presenting the follow log message:
%PLATFORM_UCAST-4-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded.
In this stack we are using the layer 3 with OSPF routing, and the current sdm prefer is default:
switch-01-3750#sh sdm prefer
The current template is "desktop default" template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.(code)

Nov 3, 2011I am about rip and replace my current 3750G stack with a 3750X stack. I have trunked over vlan and vtp info and implemented a config so it should be ready to go other then moving cables onto it. However one thing I want to correct with our current setup is that the root bridge on our vlans including vlan 1 is on a separate set of switches that we control, however I would like this new stack to be the root bridge for all of our vlans. It will be the central set of switches that all other switches trunk into. I have pre-set higher spanning-tree priorities for each vlan on the new stack so I expect as I move lines into it that the tree will be re-calculated with it as the root bridge. I've ensured that there are no root guards on any of the other switches trunks and priorities are all at default levels for each vlan. Should I enforce root guard on the trunk interfaces of the new master stack? Most of the trunks are port-channels to the other switches - do I need to set root guard on the Port channel interface or on the individual ports that make up the Port channel? On both? Any other recommendations in regards to implementing spanning-tree with the new stack? I know using port channels eliminates a lot of potential for loops but not every trunk is and I'd still like to have spanning-tree on.

Feb 29, 2012I currently have Cisco 3750G which is currently live and active and fully populated and only have remote access.
I have an additional same switch which I would like to stack. My initial plans were to have 2 GIbit etherchannels, but I came across the option to Stacks both switch with each other.
When I do a show switch on the live switch its set as a Member: [code]
I would like to add the new switch to the stack without losing the config for the switch which is live. I understand that the highest priority of the switches becomes the Master but as the live switch is Priority 1, would chancing this affect the switches config, or would it lose connection at all?
Also when I plug in the new switch and it reboot how do I ensure it becomes the slave without rebooting the live switch?The cables on the switch do they have to go to port1 on the live switch and port 1 on the new switch or can they be port 1 and port 2?

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)?

Cisco Switching/Routing :: 3750G - Stack Switching Priorities Not Correct
Mar 21, 2012I got Two Distribution Switches of Cisco 3750G. Each Distribution have two 3750G switches stacked. I also have one Cisco 3750V2 Access Switch connected to both Distribution. When I am checking for redundancy, I can only get redundancy test pass for one link not atall for other. If I have a link up with Distribution 1 only then its fine; but disappointment with Distribution 2 link. I can see that the switch priorities of Dist 2 is not correct ie. Master's priority is 10 and Member's is 15.
My question is that due to misconfigured priorities on Distribution 2 stack switches I am failing with redundancy if ONLY Dist 2 is up and Dist 1 is down.
Cisco Switching/Routing :: EtherChannel Cross-Stack Between 3750g And 4507R?
Oct 23, 2012I am running out of ports on a 4507R and would like to use a 3750G-24TS stack that I already have to expand capacity. Is it possible to configure EtherChannel between the 4507R and the 3750G stack and if so what is the best way to do it? without LACP, with active-active mode LACP or passive-active mode LACP...
This is what I have in mind:On the 4507R side I would like to use interface GigabitEthernet3/5 and interface GigabitEthernet4/5 where modules 3 and 4 on the 4507R are "6 1000BaseX (GBIC) (WS-X4306-GB)". On the 3750G side I would like to use ports 28 on both switches in the stack which are equipped with Cisco GLC-T= 1000BASE-T SFP transceiver module for Category 5 copper wire with RJ-45 connector. [URL] Cross-Stack EtherChannel Without PAgP or LACP should look like this:
3750switchstackA(config)#interface gigabitethernet 1/0/28
3750switchstackA(config-if)#channel-group 1 mode on
3750switchstackA(config-if)#switchport trunk encapsulation dot1q
3750switchstackA(config-if)#switchport mode trunk
3750switchstackA(config)#interface gigabitethernet 2/0/28
3750switchstackA(config-if)#channel-group 1 mode on
[code]....
is that what I should be doing? is there any benefit to the active-active mode LACP or passive-active mode LACP and which are applicable to the case above?
