I have a c3560 switch that has two gig fiber modules in it. I need to uplink fiber to one of these at 100mb. This is because this port will be rate limited to 20mb and 10 percent is the lowest you can go with the rate limiting command. Is there a 100mb fiber module i can insert in the 3560
Got 2 of these switch stacked and there is some changes that we are going to undertake which will require us to utilize the whole 8 or 4 (2 from each switch) SFP ports. Just need some adivce on which particular fiber modules should I procure. Does this switch support 10GB of SFP ?
We have a core switch with the following ios and supervisor engine. Can we add a16 port LR (x2)or LRM(X2) ON the core switch?if not what modifications has to be done?if an ios upgrade is necessary is it a costly affair?At present we have two 1gb up link modules in single and multimode fiber .

We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?
Here's the info:

This is the log from one switch:

I am trying to connect a SF200-48 switch via Mini-GBIC MGBLX1 fibre module to a Cisco 3750 switch with a GLC-SX-MM fibre module installed both running a 1000 Mbps. When connected together they do not enable. Are there compatibility restrictions or is it that the Mini-GBIC modules cannot be used to uplink to a LAN?
Our network administrator restricts all our new 1Gb switches to only 100Mb, to which he claims it will increase overall performance. Preventing devices from bottlenecking the network. (that is, only restricting the main switch ports, not the uplinks)For example we have a new building with 2x WS-C2960S-48TS-L connected together with FlexJack and then a 1Gb Fiber connection back to our core switch.
This building is on it's own subnet and there is little broadcast traffic. I don't see the point other than it hinders the potential speed we could use. Labs are set up in this building and 1Gb is MUCH faster when it comes to imaging and software deployment.
I have a 3560-8PC in which the mgt vlan randomly (twice in one day or 2 weeks later) goes into the down state and will return w/o any interventaion 15-20 minutes later. Int G0/1 is the uplink to a 3750. I dont think its a layer1 issue at this time since i have seen it work just fine for over 2 weeks and drop again. I don't see any errors on the 3750 either.

I have C3560 switches in my work environment. I want configure ssh on that switch but the IOS what they have 'c3560e-universal-mz.122-58.SE2' not support. As per advised I was triying to upgrade 'c3560e-universalk9-mz.122-58.SE2" for all my access switches.
I successfully upgraded for two switches.
I have two problems now
01. I upgraded the IOS successfully one Switch but the Poe is not working. What is the reason ?
02. After upgrade the IOS, the out put is as follows
I am in a doubt if the 3560-12-PC-S supports OSPF. Datasheet says we need IP Services image. But 3560-12PC doesn’t have the option with IP Services. Then I havigate to [URL] how?
So, any clues whether or not this box can run OSPF?
Switch .55 can ssh into Switch .57 but cannot ssh into Switch .56. Switch 56 can ssh into Switch 55 and ssh into Switch 57 Switch 57 can ssh into Switch 55 and ssh into Switch 56
The software on .56 is:
C3560 Software (C3560-IPBASEK9-M), Version 12.2(55)SE3, RELEASE SOFTWARE (fc1)
I noticed on .56, when I do a show ip ssh I get: SSH Enabled - version 1.5. It doesn't say version 1.99 like the others even when I configure version 2. Is this a bug I am running into?

the intent of the above is that management connections will only be accepted via SSH, and all of those will be authenticated via RADIUS, unless it's down, then it will use the local username/pw combinations, most of which are given Privledge level 15. Telnet should never work.SSH works as expected (authenticates via RADIUS), but the problem is that Telnet also works, will ONLY use the local database (never RADIUS), and, for some reason, leaves the users at Privledge level 1, instead of the configured 15.Essentially, it seems that at every point I have told it to do something that isn't the default with regards to telnet, it ignores me.Prior to a recent IOS upgrade, the switch didn't support SSH, so the previous config was Telnet with RADIUS, and that worked fine.
Had a switch die over the weekend, a c3560, per our normal procedure I pulled the hardware put a very basic config on it(vlans, portchannel, uplink ports, ip of management vlan, con and vty security, snmp, enable secret, and hostname). Then I use solarwinds orion to upload a copy of the old config to bring the switch back to the same state as the one that failed. Its a system that has worked for us 3 or 4 times in the past. But this time when the base config was on the box it couldnt ping across the network.I have tried clearing the arp cache and the dynamic mac tables, i verified the routing tables and even removed the 10.1.185.128/27 route and re-added it, saw the routing update go across to the other 65k, tried bouncing the edge switch(i cant bounce the 65k's), took down the po between the edge and 65k.
We are seeing output drops on a C3560 switchport, this port does not have QoS enabled -- application does not need special qos treatment, as long as packets are not droppd, so I suppose all traffic will share the same queue? then how should I read the output of "show platform port-asic stats drop" which indicates that it is queue 3 weight 2 drop? I am wondering what is the best way to fix this? enable mls QoS and increase queue 3 bandwidth share on this interface or just increase the output queue depth?
switch#sh mls qos interface gi0/1 GigabitEthernet0/1 QoS is disabled. When QoS is enabled, following settings will be applied trust state: not trusted
I am having an issue with VoiP phones giving me an insufficient bandwidth message. I have three remote locations connected to our main building using 2 Mb point to point ethernet solutions through TWC. Each remote location has a Cisco WS-C3560-24PS running IOS C3560-IPBASE-M, version 12.2(25) and have the cable modems plugged into port 1 on them. The remote buildings are labeled 192.168.101.xxx, 192.168.102.xxx, and 192.168.103.xxx. There are 14-16 VoiP phones in each remote building. The main building being in the subnet of 192.168.100.xxx. I have the 3560s connecting to a single port on a 2801 in the main building, all using the subnet of 192.168.253.xxx The phone server sits in our network at 192.168.100.203. I have created the ACLs, class maps, and policy maps on all of the equipment.
For the remote buildings I have the following:
ACL =========== Extended IP access list VOIP permit tcp any host 192.168.100.203 dscp ef permit tcp any host 192.168.100.203 eq 5566
[Code]....
I have put a hub in to capture traffic via Wireshark to see if DSCP flags are being appropriately marked and I do see that all VoiP packets are getting marked with as EF. However, I have been receiving phone calls from people in the remote buildings stating that their phones will cut out, flash Insufficient Bandwidth on the LCD displays and then the call will cut back in. I am wondering if the 2801 is not applying QoS with the rate-limits in mind since it is set to 100 Mb, or is it an issue with trying to take 3 remote locations and bring them down into 1 port on the 2801?
I have two layer 3 switches C3560 and C3750 Cisco switches with ios version "ipservices-mz.122-35.SE5".Now with the current ios version, these layer 3 switches are not supporting object group.so my question is , do i need to upgrade the ios, for this feature, if yes, which version ?
I need to configure the C3560-24TS, QoS control by IP or subnet.i tried to study books and videos many times but still feel i am not well known about QOs...
I have a C3560-24P PoE switch, running on a very small network with nothing special about the endpoints or the configuration (5 laptops connecting via 1 wireless AP, 1 firewall uplink, a networked printer and one conference room phone using PoE. That's it.) I actually have inline power turned off on all the non-PoE device ports.
We are encountering a very strangle anomaly where if a client attempts to send a print job through the switch, to the network printer, the printer makes a noise as it if's begun to initialize and then the switch immediately goes into a reboot. Also the reboot appears to immediately drain all he batter power from the UPS unit that it's connected to. The unit is an APC SmartUPS 750 (500W, 750VA) and when the switch reboots the load on the UPS jumps to well above 100% until the switch appears to 'level out'. Is that kind of power draw normal when rebooting a C3560?
I'm having some weird issues with our 3560 that's connected to an MPLS line. The speed of the port plugged into the providers equipment is 100Mb, but we're only allocated 10Mb of bandwidth from them, I tried to police our traffic out of the port using srr-queue bandwidth limit 10, however when I do that I get some really weird bandwidth results.
Using iperf I've run bandwidth tests with srr-queue bandwidth limit enabled and with it disabled, when it's disabled I get the full 10Mb as expected, however once I enable it I'm lucky to get 5Mb, and while the test is running connectivity between sites is almost useless (which is not the case if I disabled bandwidth limit). Is there anything special I should be doing when I have this enabled? I also have priority-queue out enabled with only one dscp marking placed in queue 1, with very little traffic hitting that queue, but regardless of what I do I can't get the expected bandwidth with the bandwidth limit command, even if I place my iperf traffic in that priority queue.
I need to replace an older 3560 with a new 2960-S and am wondering if the SX SFPs I already have will be compatible with the 2960-S. [code] I cannot find any way to get the part numbers of the SFPs.
My clients switch is running out of Spanning-Tree instances (c3560 only supports 128 instances). I know that running RSTP with VSTP can mitigate this that all instances over 128 will be handeled by RSTP, but before I implement this are there any other thoughts out there on how to mitigate this. Would MSTP be able to handle more STP instances or MISTP perhaps?
I have a c3560 that on Port 1 I can not get any device to talk to the DHCP server.Previously there was a client connected to this port however over the weekend he stated he lost connectivity.
In my troubleshooting I have connected that client to another port and now he is good to go...I connected my laptop and tried to connect to the network however I could not.I checked the logs and did not see anything that lead me to think it was having problems.
Is there another way to shut this down and hopefully start it back up without having to restart the entire switch?
We have Three locations (A,B,C) across campus. Location A is Main Location, While B & C are remote locations. Distance among all locations approx. 2 miles.
I want 10G Fiber among these three locations. I am taking 4510+E with SUP 7E with Redundant SUP & 10G Fiber line card(X2 10G) at Location A.At Location B & C, i need Max. 2 Nos. of 10G uplink. i am taking 4507r+E with redundant SUP 7LE. Can i terminate 10G Fiber UPLINK from Location A in to Redundant SUP 7L-E(10G SFP+) at location B & C ??
At one time, Primary SUP 10G uplink should be active & Redundant SUP 10G uplink should be standby. When primary SUP fail, redundant SUP 10G uplink will be active. Is that Possible with this scenario?Is that possible that at same time, 10G Uplink on both SUP 7L-E be Active?
We have two switches of the same model (WS-C3560-48PS-S) that are not providing PoE. I'm trying to remotely determine what the cause of the issue is.

When you aggregate multiple fiber GBICs together on the 3508G, do you configure it as an etherchannel, or as fibre-channel? I've looked around online for hours, but can't find it mentioned anywhere.
