Cisco Switching/Routing :: EtherChannel On 3750G-16TD-S And 3750x-48T-S With 10GB

Nov 20, 2011

Any experience with bundling a 10GB interface on a 3750G-16TD-S with a WS-C3750X-48T-S with a 10GB interface. I have worked with 5 different TAC engineers and so far I have not gotten an answer on why the switch will not let me bundle the 10GB with another 10GB interface.
 
Same switch Stack – not a cross stack.
 
Tried every configuration possible with no luck.   I originally thought it might be the stack-ring speed – I corrected that today and it is running at 32GB –
 
The only thing I can think of now is it might be a hardware limitation on the 3750G-16TD-S ?
 
Q. What performance of the 10 Gigabit Ethernet port on the Cisco Catalyst WS-C3750G-16TD switches?

A. The Ten Gigabit Ethernet uplink on the Cisco Catalyst WS-C3750G-16TD switches is 1.25:1 oversubscribed and provides maximum throughput of 8Gb/s.   –

Cisco Switching/Routing :: 3750x 12.2(58)SE2 IPBASE 10gb Uplink Ports Not Being Displayed

May 28, 2012

we have just purchased a few 3750x's that we intend to add to our 3750g stacks.  We've purchased the 10gb uplink modules, C3kx-nm-10gt, but when they are installed they are not appearing in the switches web gui nor can you configure them correctly.  If we upgrade a 3750x to 15.0.1 they seem to work fine.  All of our current 3750g's are running 12.2(58)SE2 IPBASE so we don't really want to have to upgrade them all to 15.0.1
 
Are we missing something or do the 10gb modules only work properly with ios 15.0.1?

Cisco Switching/Routing :: EtherChannel Cross-Stack Between 3750g And 4507R?

Oct 23, 2012

I 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?

Cisco Switching/Routing :: 3750x Changing Etherchannel Load Balance Configuration

Oct 24, 2012

I am installing a several new Cisco VM servers. The VM hosts are losing connectivity when we apply the etherchannel config in the core stack.  VMware has stated that the etherchannel load balance needs to be src-dst-ip in order for the etherchannel to work.However, my current stack has 2 etherchannels configured to other switches through out the bldg in network closets.  The current load balance configuration is src-mac.My question....when I make the change to src-dst-ip, will my network connectivity go down?  I saw there was an older article on this that doesnt provide an answer just a work around.  Here is the article. [URL].

Cisco Switching/Routing :: 3750g And 3750x High Memory Utilization?

Jun 11, 2013

We had a stack of 4 qty 3750g running IP base on ver 12.2.32, then installed a 3750x to the stack and upgraded the whole stack to 15.0.2 SE3. In doing so, we noticed that the memory utilization jumped from 60-70% to 83-84%.
 
We had the same issue occur when upgrading to 15.0.2 SE3 on another stack that was 6 qty 3750g running ip-services, but this one jumped to 90%.  On the 6 qty stack, we downgraded to 12.2.55 and the memory util went back down to 60-70%. 
 
On the mixed stack, we replaced the 3750x with another 3750g and downgraded the whole stack to 12.2.55, however, the memory utilization did not drop down.  As far as I can tell, no config changes have changed from the original IOS.

Cisco Switching/Routing :: Upgrading Firmware On Mixed 3750G And 3750X Stack

Jul 3, 2012

I've got a mixed stack as follows:

Switch 1 - 3750X-24P
Switch 2 - 3750G-24TS
Switch 3 - 3750G-24T
 
Running 12.2(53)SE2, IP base.  Now I tried upgrading the firmware on the entire stack to 12.2(55)SE4 and ran into this error:(Command: archive download-sw /imageonly /overwrite /allow-feature-upgrade tftp://10.20.20.13/c3750e-universalk9-tar.122-55.SE4.tar)
 
 Error: The image in the archive which would to used to upgade system number 2 does not support that system type.I haven't as yet removed the "3750G-24TS" switch from the stack and re-tried as yet, however, is the expectation that without the 24TS, the upgrade should work?

Cisco Switching/Routing :: Stacking 3750g And 3750x - Hardware Version Mismatched

Jul 18, 2012

I am trying to stack a 3750g with a 3750x. At the moment they will not stack with their current IOS as the hardware version is mismatched.
 
According to various posts this is possible as long as the same IOS is in use. The following IOS are currently in use:
 
3750g     -     c3750-ipbaselmk9-tar.122-55.SE5
3750x     -     c3750e-ipbasek9-mz.150-1.SE3
 
I have tried to downgrade the IOS on the 'X' to 122-55.SE5 however, i get errors regarding firmware incompatibility.
 
I am unable to upgrade the IOS on the 'G' to 150-1.SE3, as the size of the IOS image is larger than the available flash (Version 15 IOS for the 3750G (c3750-ipbasek9-mz.150-1.SE3.bin) is 16,074,189 bytes whereas the 3750G has 16MB of flash memory or 15,998,976 bytes total which mean the IOS will not fit).
 
Has not actually stacked these devices successfully? I understand there may be license implications of upgrading to 15 but at the moment I just want them to stack!

Cisco WAN :: Load Balancing Over L3 Etherchannel With 3750G

May 18, 2011

Here's the proposed network I have to work with:  LAN A >> ASA Cluster >> 2x3750G Stack >> Cross-stack L3 Etherchannel (2x100Mb Circuits) >> 2x3750G Stack >> ASA Cluster >> LAN B  Company policy governs that traffic between LAN A and LAN B must now be encrypted. ASA Firewalls have been purchased in advance and will be place into the network as above.   Src-dst-ip load-balancing is currently in place on the Layer-3 Eherchannel.  How can I encrypt the traffic using the ASAs and still ensure proper load-balancing over the circuits?  I was about to configure a IPSec/GRE Tunnel between the ASA Clusters but I'm concerned that the tunnel will not be load-balanced over the ether channel based on the single source and destination IPs I will need to configure.

Cisco Switching/Routing :: 4500 Can Connect 10Gb SFP+ To Standard 1Gb SFP

Nov 15, 2011

I'm looking at provisioning a Catalyst 4500 with a WS-X4712-SFP+E module to allow for future 10Gb connectivity via 10Gb SFP+ interfaces.  These cards are backwards compatible with standard 1Gb SFP interfaces but I'm wondering about the other way around; ie. can you populate these blades with 10Gb SFP+ interfaces when they connect to Catalysts with only 1Gb SFP interfaces at the other end? 
 
The data sheets don't really explain this.  It seems pointless getting 10Gb SFP+ interfaces for the 4500 when it's only 1Gb at the access layer end, but these access switches will be replaced in the near future (~12 months) and if the 10Gb SFP+ interfaces support connections at 1Gb speeds upfront, it would mean I could retain these interfaces when the access switches upgrade to 10Gb connectivity capabilities down the track. Does the 10Gb SFP+ interfaces are compatible with 1Gb SFP's or only other 10Gb SFP+ interfaces?

Cisco Switching/Routing :: 3750 Stack - 10GB And 1GB Connections

Cisco Switching/Routing :: 5596 - Extending 10Gb/s LAN Between Sites

Dec 14, 2011

For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
 
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?

Cisco Switching/Routing :: Nexus 5548 10GB-LR Interfaces Not Coming Up

Jun 21, 2012

We are trying to connect 2 nexus 5558UP (5.1.(3)N1(1)) with 10G-SFP+-LR interfaces. The interfaces are not genuine cisco's (smartoptics) but as far as we can tell, they are accepted by the hardware. If we take a look at the optical levels, we can see that the switches can see eachother (double-checked by bringing down one interface to see if optical levels really disappears) on optical level, well within limits. I found a notice about changing debounce timers but this doesn't work, setting it to 0 or 1000 doesn't make a difference. Copies of the different show int commands can be found at the end of this text.
