1) How do we monitor 3750 stacking port in LMS?
2) Let say if I stack 3 switches, middle switch should be Master. Uplink should be at Top and Bottom. Is best practice?
3) Can we mixed 3750G and 3750X and what is result internal BW - fallback to 32Gps?
4) is there any Qos difference between WS-X6816-10G-2T and WS-X6816-10G-2TXL?
5) is there any Qos difference between MSFC5 PFC4 and MSFC5 PFC4XL?
6) What is main difference between PFC4 and PFC4XL in Sup2T?
7) Pls share more about Central and Distributed Switching in Sup2T and which card support Distributed DFCXL?
The internet connection at our business goes down overnight, every night. We then have to turn off the router and turn it back on. It is not the fault of the ISP, but some setting somewhere, either in the router (SG 310 Snapgear) or in a particular program being accessed each night. Fact is, for the time being we are just trying to find out the precise time when this happens, so we can find out a reason. Is there a utility that can monitor the status and tell you at what exact point it stopped?

View 1 Replies View RelatedWe have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
is it possible to shutdown a specific port on my 3750x and monitor this port at the same time .for example , im dealing with a mac authenticated network using port security , i want to shut down all the ports that are not used at the moment , however , if some one gets connected to the one of the shutdown ports i want to know the mac address of the user or atleast to know that i have someone who is just plugged in to the one of the shutdowned ports .

Is the subject line status correct? I have a gigabitethernet port (3845) that went from admin down, to reset and then status Down, protocol Down. Then I had another gigabitethernt port on a different 3845 router. To show port in status of UP and protocol Down, I didn't see a reset occur on this port. Which status is correct and does the reset step affect the final status being different?

Now, correct me if I`m wrong but my switch only has 24 ports and two of those (23 and 24) are dual personality jobbies!?Where the hell is port 26? Where did it come from? and why did it need to show up only for the switch to realise that it doesn`t really exist?
We have cisco 7600 Router with 76-ES+XT-4TG3C Module connected. The Module is getting detected after upgrading the Router with SRD5 IOS.Below are the testing which we have done on the Router but we are facing the issue while configuring the Transport mode LAN and Transport Mode WAN:Brief about this is:- 2 Cisco 7606-s Router with Module 76-ES+XT-4TG3C each.- two ports on 7606-s Ten2/1 & Ten2/2 are configured as a Transport mode WAN while Ten2/3 & Ten2/4 are configured as Transport mode LAN.- We connect Fiber Cable from LAN Port to MUX and from MUX to 2nd LAN Port of the same Router. Same thing we tested by using the WAN Port-MUX-WAN Port connection.- Now on MUX end LAN port, connected Single and Multi mode fiber and on 7606 end 2/4 port which is configured as transport mode LAN, using Multimode SFP module -> XFP-10G-MM-SR, port did not came up then replaced 2/4 port with single mode SFP ->XFP-10GLR-OC192SR port came up. this is testing for LAN.- For WAN testing on MUX end used WAN port and on 7606 end checked with single mode and multimode fiber and with single XFP-10GLR-OC192SR / mulimode XFP-10G-MM-SR SFP, port did not come up.Wanted to know 1) If we have to go for Transport Mode LAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.2) If we have to go for Transport Mode WAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.Anything else is required while configuring the Transport Mode WAN as this is for Packet-Over_SONET/SDH? 3) MUX Side change is required while connecting both of this Modes on Cisco 7600 Router.4) Is hardware of the Router is giving any issue? Though we tested by connecting Back to Back LAN Port as well as Back to Back WAN Port. In both the situation the Ports are coming UP.
View 1 Replies View RelatedWe have two 6509 switches with one WS-X6704-10GE module in each of them. There is an optical cable between the two switches plugged in WS-X6704-10GE module on both sides. When you shut down the port on one side the other port still stays as up and you need phisycally to unplug the cable to have it down. The same behaviour is seen no matter on which of the two switches you shut down the port, the opposite one always stays as up and only removal of the cable makes it go down.
The ports are configured quite simply:
interface TenGigabitEthernet1/1
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-10
no ip address
udld port
The IOS version is 12.2(18)SXF8

I am having some problems creating a SPAN port on my Cisco 871 (running IOS 12.4-11T).

View 5 Replies View RelatedI was wondering if there is a workaround to have a mac access-list bond to a port security violation action our need is the following: we have a range of 10 mac addresses that can use any port on the 3750, we only want to allow those ones yet we also need to tak action if a denied mac appears on any port of the switch.the only work around I found is to basically go into a port-rage mode and list all the allowed mac addresses under all the ports of the switch. I would also add to that a port violation action. did not test it but should work. problem is, it would be a huge config.I did read that we can create a mac access list and then bind that mac to physical ports wich will actually simplify our solution yet I did not find a way to bind the mac list with a port violation action.
View 1 Replies View RelatedWe are using 3750 switches as WAN router facing the WAN cloud. To configure QoS for its WAN port, should I use 'auto qos voip trust" or treat it like a router port and configure class-maps, policy-maps, and attact service-policy input or output?
Because switches have different queuing and dropping methods than routers, auto qos can generate QoS configs that are considered most appropriate for 3750 switches. However the switch functions as WAN router. Maybe it should be configured using router type of QoS with policy-maps and service-policy?

View 1 Replies View RelatedWe use Orion for monitoring. We recently started monitoring a workstation switch and find many occurances of port speed changes indicated. Our workstation ports are configured with auto speed and duplex. Is it normal that we are detecting speed changes on the ports? Do workstations running XP automatically adjust their speed for traffic management or power save? Perhaps something like speeds changing when PC goes to sleep mode but has wake on LAN enabled? Is it possible that the MIB is misreporting?
I realize that there are many different NIC vendors/drivers that might act differently. Just wondering (in others experience) if it is somewhat normal or if there is anything on network I should be looking into as to why speeds are changing? We plan to not monitor workstation ports (only uplinks) on the switch.. but before we do, I thought I would see if what we are detecting needs to be addressed?
Here is an example from Orion of a speed changing. Seems always off hours:

I have disconnected Port 1 Switch 4 and connected it to Port 2 Switch 4 and then Switch 4 came back online. This made me think Port 2 on Switch 4 was working correctly. Then I disconnected Port 2 Switch 1 and connected it to Port 1 Switch 1 and then Switch 1 came back online.
have a cable i think is bad, is it possiable to switch the cable out without causing any downtime to the switch or connected devices?

There are two Win7 SP1 PCs (A & B), plugged in to a 3750-x (v12.2-58-SE2), on ports 33 and 41.
The ports are configured for 802.1x, auth order of MAB then Dot1x. Priority is Dot1x, MAB. The config is the same on both ports (verified at show run all).
When either PC is plugged in to port 33, everything works as I expect. Client sends an EAPoL message, gets a response, and is authenticated. When PC A is plugged in to port 41, same correct result. When PC B is plugged into port 41, the client sends an EAPoL start, and the switch never replies.
If port 41 has the authentication order changed to dot1x then MAB, PC B works fine.
