Catalyst 4948 and 3750
We are looking at using a Cat4948 for a small data center and by looking at the specs it appears to be far superior than the Cat3750. But why is the 3750 priced higher, I keep thinking that we are missing something. Is there some features that the 3750 has over the 4948?
Hi,
The 4948 has redundant & hot swappable power supply and fan modules.
THe switching capacity (96 GBPS) is also more compared to the 3750(32GBPs). It is based on the 4500 model and gives you wire speed performance.It is the high end switch cisco has to offer in fixed configuration model.
The 3750 on the other hand has stacking capabilities. upto 9 switches can be stacked together and can be treated as a single switch operating on 32 GBPs backplane.
In a nutshell,If you want to use the switch for Layer 3 purposes i would suggest 4948.
but if you want a high density L3 switch but cannot afford a 4500 or 6500 then u can go for multiple 3750s and stack them

How to make optical connectivity between Catalyst 4948 and 10K router ?
Hi,
I am Ratheesh P D, network Manager of one project in Motorola. We have one catalyst 4948. Its going to get one 10K router. Our requirement needs optical connection between these two. The document of 4948 says, its compatible with 1000BaseX SFP and 10K is with 1000BaseSX SFP. Could you please tell me how to make these two compatible?For information regarding the optical connectivity in 4948 cat switch follow the url ,

Etherchannel suspended between Catalyst 4948 and VSS 6506E
Hello,
I describe an issue when i need to performe an L2 or L3 Etherchannel from a Catalyst 4948 IOS Enterprise and 2 xCatalyst 6506E bandled with VSS.
From the VSS Side when i plug cables i see on the physicals and Etherchannel that Physical and protocole layer are up. On the 4948 side,
I see that physical layer is up and protocol and Etherchannel interfaces are down.
On the Etherchannel port summary i see that the port state is supended.
On the first attempt, i have test with a L3 etherchannel on both side using no switchport with two IP addresses one at each side on etherchannel interfaces.
The etherchannel are bundled with LACP mode active and on the second attempt with PAGP mode ON.
The same configured on VSS 6506E work fine with Catalyst 3560E.
Please do you have any idea?Hi David, when ı type "no mls qos channel-consistency" under port-channel
the issue was solved. But ı am not comfortable with that, Because ı want to use Qos feature
here the "show module all"

Catalyst 2950 and 3750 console not responding after successful boot
i just removed two switches from my ccie R&S lab but now i has a very strange problem switches is working fine but i can not access from console after boot .
Do you have any other devices you could use to check your terminal emulator is working? I had an issue with hyperterminal once, that it would not transmit following a reboot of the device it was managing. But in my case, re-booting the PC (with a proper power cycle) cleared the problem, so it couzld have been something to do with flow control.

Comparison between 3750 and 3750-metro
hi folks,
is there any links which will provide me on the comparison between 3750 and 3750-metro? for exapmple, isis is not support on 3750 but it support on 3750-metro. The product information from cisco site is insufficient in term of the main differences :p
rgd
josh.wHi Josh,
The Cisco Catalyst 3750 Metro Series is built for Metro Ethernet access in a customer location, enabling the delivery of more differentiated Metro Ethernet services. These switches feature bidirectional hierarchical QoS and Traffic Shaping, intelligent 802.1Q tunneling with class-of-service (CoS) mutation, VLAN translation, MPLS, EoMPLS, and Hierarchical Virtual Private LAN Service (H-VPLS) support, and redundant AC or DC power. They are ideal for service providers seeking to deliver profitable business services, such as Layer 2, Layer 3, and MPLS VPNs, in a variety of bandwidths and with different SLAs.
The metro switches have the PXF chips (which allow hierarchical QoS on the 2 "WAN" GigE ports, so several logical links can share a connection, and have soft bandwidth limits).
For more details on 3750-M switches have a look at this link

Last edited by arastoo.s (2011-02-13 14:04:57)As far as I know catalyst-daemon and catalyst-hook provide the same module so they are in conflict. The difference is that catalyst-daemon uses a daemon at startup to check for a new kernel and compile a new module when needed. Catalyst-hook does the same thing with a hook.
I picked the daemon method and just answered no to replace with -hook or -generator (catalyst-generator also conflicts with the others). Just choose the one you like.

How often should the 6509's and 3750's switches be rebooted?
Does Cisco have a best practice document on this and recommendation how long the switch should be up before it gets rebooted?
Why is a reboot needed if there are no indications of issues on the log?I'd agree with Larry here.
If you're not seeing any issues with your IOS revision and there are no relevant PSIRTs (security notices applicalble to features and or exposure of your device requiring an IOS upgrade) then you can go a very long time without rebooting, if ever.
I'm sure it's far from a record, but our corporate distribution router that supports >1000 downstream devices day in and day out has never been rebooted since installation just over 5 years ago. I have a top of rack Layer 2 switch (2900 series running CatOS) that's almost at 10 years.
That said, you should have some monitoring scheme that assures you everything is healthy. But as long as memory and cpu are happy, the device will run forever. -

The post I linked to https://bbs.archlinux.org/viewtopic.php … 4#p1330764 says
You're doing an update and something is trying to install mesa-libgl which conflicts with the already installed nvidia-libgl.
Find out which package is it.
In your case it conflicts with catalyst-utils, not with nvidia-libgl.
You cant deny that they are really similiar, I didnt note, my bad.
How can I find that package?
I cannot remove catalyst-utils, as I need to use that..
Yes, I knew it conflicted with catalyst-utils that why I made a new thread. In that thread it got solved by waiting. For me, Im having this problem since some days, and now I got some time to post here and try to fix it.

I have a creative cloud membership. If I don't want to build a site in Muse, can I build a business Catalyst site and have hosted free with my creative cloud membership?
Yes you can! It is a Basic level site but you can build it without Muse. I think you may need to create the site originally with Dreamweaver or Muse (meaning creating the site with Business Catalyst not building the site) but once that is done you can use any software to create the code for the site and upload it via SFTP. Hope that makes sense.

Catalyst 2960 and SGE500 switches
Hi,
Can we on the same network use Cisco Catalyst 2960 and Cisco SGE500 switches and share the same VLANs ?Hi,
I didn't find VLAN support in key feautures of SGE500 but I'm sure it is there. For VLAN sharing you must configure trunk between switches. The number of VLAN must be the same (exluded some cases).
For sharing VLAN information (VLAN count, names etc) the switches must support VTP protocol, not sure that SGE500 support it. But VTP is not necessary for trunking between switches. -
