Cisco :: 3750G-48 Good Sources Of Information To Program And Configure This Switch
Dec 24, 2012
I am a very basic user on the Cisco Switch programming. I was given a Cisco 3750G-48 to tinker with in my home office. I was wondering if someone could lead me to some good sources of information to program and configure this switch? I am wanting to create a GB network in the house with the computers that I have and the storage arrays.
I use the Switch 2960S support PoE and 10 access points cisco.I have one more question:
-- If all 10 access points cisco use copper cable to connect to 2960S, 5 access points use power adapter and 5 access points use power from Switch. How Switch 2960S will provide power for 10 AP or switch 2960S will understand and only provide power for 5 APs?
I'm having issues with SSH on my 3750G-12S. I'm not able to SSH to another switch when VRFs are configured.I've tried ip ssh source-interface, ssh -vrf doesn't exsist and I've upgraded the IOS to the latest version.
We're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?
We have an SG300 managed switch located in a small business of less than 10 PCs. There has been an ongoing issue with Internet speed. Is there any way that I can monitor the router for traffic so that I can see what might be causing the problem? I would like to focus on the WAN port and Internet activity particularly.
I'm trying to set up QoS between a 2811 router and a 3750g switch. I'm currently using the 3750 as the router for one side, having the interface connecting to the router as a routed interface.
I have this config on the router side:
class-map match-any IPTel-Traffic-CL match ip dscp ef match ip precedence 5
I plan on starting a high speed LAN for my Gaming LAN party's. We send 100's of GB of data over our LAN networking when we do this, so i need a good switch that can handle the stress of the massive data transfers. It needs to be a gigabit switch and at least 8 RJ45 ports.or is there a different one i should get all together? i cant spend a butt load. url...
Is it possible to view extensive information about switch supervisor on WS-C4506 platform? I could use show module or show inventory, but this only displays the module name. For example how to view the amount of SRAM the SUP has? Or any other similar more detailed information?
I am trying to buy a GLC-SX-MM SFP module via Fed Stock, and I keep getting a GLX-SX-MM. What is the difference between these two part numbers? I can't find it on the Cisco Web site and eve a search of Google comes up relatively fruitless! Is the GLX compatible with my 3750G-24PS switch?
I am having a switch 3750G (WS-C3750G-24TS-S) running a software version (c3750-ipservicesk9-mz.122-55.SE6.bin) and using the PBR with IP SLA.While, i am applying it on interface, it says not supported....
route-map TO-CAS-E0 permit 10 match ip address 125 set ip next-hop verify-availability 10.116.199.200 10 track 100 (if i change this command to set ip next-hop 10.116.199.200, it works) ! WAN-L3-3750SW01(config-route-map)#interface GigabitEthernet1/0/11
I have one switch 3750G12S I joined the company new, I found that they want to replace it with Alcatel stack switches. I didnt configure this Cisco switch before. how to configure it. I have 4 other new cisco switches in the topology which is not created yet. the 4 switches are all 2960.
have 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)
I'm due to replace a stack of 2 x 3750 switches very soon with 2 x 3750Gs. These 2 current switches are the VTP server for a small domain. I have put the config on the new switches switches and I made it a server and used the same VTP domain and password etc and got the VLAN info ported over.Now I did this a while back and noticed the switches are in transparent mode with a revision number of 0, I need to set this back to server and swap the switches out but the revision will be lower than the client switches (around rev 200), what do I need to do?
I am having an issue bypassing a switch 3750G series. How i can bypass the old configuration in the switch.i have tried the CTRL+BREAK at startup but it wont work.
I am looking few information on IOS up-gradation for the switch WS-C3750G-48TS-S . I loaded new Image on the flash and current flash and sh boot as below
1) I would like to set boot sytem parameter for the new IOS and secondary old IOS as well is below command works??? if IOS not coming up with new one 12.2.58 is it boots with old 12.2-35 ?
boot system flash:c3750-ipservicesk9-mz.122-58.SE2.bin;flash:c3750-ipbase-mz.122-35.SE5
2) If I set only boot system flash:c3750-ipservicesk9-mz.122-58 , if new image corrput swicth will check valid image and boot up with old image ?
3) If switch went to room1 switch mode and still I have valild running IOS c3750-ipservicesk9-mz.122-37.SE.bin at flash memory, how to restore with old image
Has any come across show ver memory details on 3750G-48PS as below, One of our Catalyst 3750G running software 12.2(44)SE2 shows unexpected DRAM as below:
cisco WS-C3750G-48PS (PowerPC405) processor (revision F0) with 0K/12280K bytes of memory. This would equate to around 11MB memory which does not seem right... Is it a known IOS bug?
The two stacked Cisco 3750G Access switches on a particular floor in my coy just lost connectivity to the distribution Switch this morning. This meant that all Users connected to it couldnt connect to the Internet nor access local network resources.I couldn't ping the Switch IP, I couldn't also access the Switch via Console port. Each time I tried to gain access via the console port, I keep getting "Authentication Failed" message.What should I do next? How do I gain access to the Switch?
I 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.
I wan to migrate from a router 2800 to L3 switch 3750G , the thing is that we have several vlans and we use a router sometimes with each interface configure with correspoinding vlan subnet ip to route traffic between vlans there is no static or dynamic routing only directly connected interfaces on router routing traffic to each other ?How would i configure a L3 switch interface for simillar functionality , below is my current router configuration
! ip domain name yourdomain.com multilink bundle-name authenticated ! vtp mode transparent
I try to connect two switch Catalyst 3750G without success.switch1 (192.168.2.10 vlan 2) <=> (192.168.2.11 vlan2) switch2.I use this configuration for swich1 [code]
I am cascading one new switch 3750G (int Gi1/0/1) with an existing 3750G (int fa1/0/26) switch.. But the interface fa1/0/26 goes in err-disable state even after NO SH.. also i have diable Spanning treebpdu guard and disable spanning tree portfast. But still the issue is not resolved.
I 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?
In the Firewall Dashboard of my ASA 5580, I get data on every pane, except for the Top 10 Sources and Top 10 Destinations. Why is that, and what do I need to do to get data there?
