Does the Network Module "C3KX-NM-1G" and "C3KX-NM-10G" for Cisco Catalyst Switch 3750X Comes with a transciever like GLC-SX-MM or SFP-10G-SR or do I need to order in seperately.

Is it possible to mix 1 and 10 Gigabit links on a 1/10Giga Network Module of the Cat3750X? I mean porte GE1/1/1 and GE1/1/2 used with SFP and port TE1/1/2 used with SFP+; that makes TE1/1/1 not available as GE1/1/3 and 1/1/4

View 1 Replies View RelatedIt seems I have seen this before (and even done it once a few years ago).. but it has been a while. I have a stack with a Cisco 3750 stack that I have to replace a member.The replacement switch is a 3750X.
I think I have to upgrade the IOS of the older switch to be the same as the 3750X.
Current switch: WS-C3750G-48TS 12.2(46)SE
TO BE ADDED WS-c3570X-48 15.0 (1)SE2
It seems to me there was a way to upgrade the older switch IOS from the newer switch or downgrade the newer switch with the older IOS.I dont have the Cisco account to download updated IOSs.
I have RFID Reader (10.10.63.2 - 255.255.255.240) connected Cat-6 POE to ws-c3750x-24p-s - standard TCP/IP web service app pulling data from the reader every 250msec: I have my app server connect via vlan by ws-c3750x-24p-s IP address (128.1.70.1 - 255.255.0.0) as you can see its on a different sub net;
I can ping the device from the server - although I'm not getting any data coming through: my config are as:
0 [switch 1 provision ws-c3750x-24p-s]
1 [system mtu routing 1500]
2 [ip routing]
3 [no ip domain-lookup]
[code]...
I can ping the device from the server - although I'm not getting any data coming through.
Any pointers on configuring security on a Cisco 3750X switch that sits on a public (WAN) network. It will distribute connectivity to individual ASA firewalls as there are only two main links from upstream. Obviously I'll be disabling the http server, SSH (besides the management interface), etc.I know I can create ACL's, but worried about performance? I'm looking at blocking Netbios and other protocols that are not nessesery on our network. I've been told to disable the default VLAN... is that a good idea? And instead use the management port? I've looked around but there doesn't seem to be much information about what you should enable or disable on public switches.

View 7 Replies View RelatedAt our site we have a 4510 core switch and 3750x switches in our IDFs. The 3750 switches are connected to the core via DOT1Q trunks in a server client setup. We are putting in an Informacast/Berbee server witch will send pages and text to the cisco phones. We also have 1 3750 switch connecting to the core via a layer 3 port channel. If we put the Informacast server on the phones vlan would I just need to enable ip pim sparse-dense mode on that vlan only and enable multicast routing, ip multicast routing?

The process "HL3U bkgrd proce" is causing high CPU usage issues in a switch 3750X-24T-L. The IOS is 15.0.2-SE2.

I have a 3750X 24 port switch (with NM-1G network module) running IOS 15.0(1). Is there any benefit or reason to plug in the included Stack Wise cable and loop it back to itself in a single switch installation?
I don't see any recommendation in the documentation. The data sheet indicates a single switch is a non-blocking device so I'd think there's no bandwidth advantage like there is when connecting an actual multi-switch stack and needing to close the loop for the full 32 Gbps stack bandwidth.
About an hour ago I had the master switch on one of my 3750x (WS-C3750X-48PF-S) stacks crash. The only two items we've found that could have caused this issue are the roughly 1.3 million big buffer misses and several of the following in the syslog
SLT:WARN:No exporter configured for smartlog! I do not have smartlogging turned on, nor is there a netflow exporter configured
sh logging smartlogsmartlog is disabledsmartlog exporter:smartlog pkt length: 64 Total pkts processed: 0Total DHCP Snooping pkts processed: 0Total DAI pkts processed: 0Total IPSG pkts processed: 0Total ACL pkts processed: 0
I did not see any traffic spikes prior to the crash.
This stack has been stable since it's last IOS upgrade from 12.2(58)SE1 to 12.2(58)SE2 back in October 2011 so this has me a little worried.
I am having issues (nothing new there) I have a bad IOS on a switch module, and the config is set to boot to that IOS, and as such I get a nasty boot loop, I am trying to figure out how to get into rommon but all the documentation I can find for this just says go into rommon and never tells me how to get there on a switch module that thinks it has a good IOS. (The IOS is for our normal service module but this one is an odd-ball switch)

I've 3750X switch that isn't loading email. then I went to rommon mode and accidently for "format flash". after that I loaded 15.0 SE2 s/w on it using tftp server but it doesn't boot up with that image. flash had only .bin file after I loaded it from tftp server.
since it wasn't booting up, I did format flash again and thought to load image again from tftp server but now, it doesn't load image from tftp server.
I have a 3750X four-switch stack acting as the core of a fairly simple LAN. All I need to achieve (and this seems inordinately hard, but it is entirely likely that I'm just being dense) is to get access to the internet through my core switch, through the firewall and out through my VSAT. I've spoken at some length with the firewall providers (Cyberoam) and they tell me all I need to do when I migrate onto my new system (Cyberoam is currently in place at the entrance to our existing LAN) is change the local IP address of the Firewall, plug in the new switch to the LAN port, and away I go. Tried that, didn't work, so obviously I'm missing something.

I work at a hospital and we have 3750X-48P switches in stacks in various locations throughout the hospital. We have noticed that when an EKG machine is plugged into one of the ports on some of these switches and the EKG machines are set manually to 100/Full, the ports are no longer usable until the switch is restarted. The switch is configured for auto. If the EKG machine is set to auto, it will work and not cause problems. The link on the interface will show up/up and there will be output packets increasing. However, there will be no inputs on the link and the port is unusable. Unfortunately, even when the device is removed, the port becomes unusable for any device. Is there any way to fix this problem without rebooting the switch?

Due to cabling issues, we have a switch (Switch F) that we can't connect directly to the 3750X so we have it connected through another switch. Everything is set to VTP client with the correct domain and password but this not-directly-connected switch isn't receiving any VTP VLANs.

We have 9 x 3750x switches with 5-nonPOE and 5-POE. There is a limitation with 4 POE per stack with Stack Power.
Can we combine all 9 to one stack since there are only 4 POE?
Or, is the 4-switch limitation applied regardless if they are mixed with POE and non-POE?
We have recently purchased some Cisco 3750x switches and we are getting complaints from users that the performance is poor when both the PC's NIC and switch port are fixed at 100/Full?
There are no errors or collisions on the switch interfaces so there is no obvious problem on the switch. The PC's are standard DELL Optiplex 755/760's
or gx 520's.
Any performance issues when configuring the switchport to 100/FULL?

I want to limit the bandwidth going to remote site on the switch connecting to our netapp.We have a 4 port channel group setup on our 3750x switch going to our netapp storage. We have a Wan 100mb link to our remote site and we want only 60MBs of that link to be used for Netapp traffic all other local traffic needs to use the full amount of the bandwidth to the netapp.
Is possible to allocate bandwidth in this way and how would I go about this? We dont have access to the routers for the link and they plug directly into a port on our cisco.
Two Cisco 3750X can be stacked together to ensure redundancy.Is the attached topology feasible for access layer redundancy?
