View 7 Replies View RelatedWe 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?
I have a Sup32 that I suspect has faulty NVRAM (e.g., I am unable to "wr mem" on the device - it states resource is busy but no other active connections exist). Prior to replacing the supervisor engine I'd like to take a crack at formatting NVRAM to see if it resolves the issue. This supervisor does not have a CF card installed, thus no Disk0:. Within the CLI, I am presented two options with the "format" command - bootflash: and sup-bootflash:. Bootflash: does not have any data on it, however, sup-bootflash: contains my IOS image. I believe that both of these locations are simply directories within NVRAM.
View 3 Replies View RelatedI am considering running stacked 3750 L3 switches as the edge of the network, which will connect to the ISP. The ISP would hand off two lines with one to each switch and two lines to each client zone. Does running HSRP, running port channels, or running routing protocols seem like the best option for redundancy?
Lastly, will the 3750 provide all the QoS I should need for restricting each client zone's bandwidth both up and down? Could I get away with a lower model and still get these features?

View 1 Replies View RelatedI am little confused about the location of FIB table and adjacency table in both cisco 6500 series and fixed ports switches .In case of 6500 series switches
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor,and the route processor performs the express forwarding. Use this CEF mode when line cards are not available for CEF switching, or when features are not compatible with distributed CEF."
If line cards do no support CEF, then FIB and adjacency tables are built and are located on route processor( control plane ). Data plane operations are implemented in software and route processor performs those operations.
Some Cisco switches actually use different hardware to control the different planes. For example, the Cisco Catalyst 6500 is a modular switch that uses the Multilayer Switch.Feature Card (MSFC) for control-plane operations, and the supervisor Policy Feature Card (PFC) for the data-plane operations.
Supervisor module has has MSFC and PFC. MSFC implements control plane operation where as PFC implements data plane operation.But the first paragraph says in Central cef mode, both data plane and control plane operations are implemented by route processor. [code]
Do these switches implement the Central mode cef in same way as mentioned above. i.e
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor and the route processor performs the express forwarding. Use this CEF mode whenline cards are not available for CEF switching, or when features are not compatible with distributed CEF."Or fixed ports switches such as 3750 implement data plane operation in hardware where FIB tabe and adjacency table are maintained on Data plane.
My management has tasked me to give them a high level overview of the different switching we can choose for our new building.

View 2 Replies View RelatedI have a stack of 2 x 3750X switches these are running 12.2(55)SE5. I needed to add some static IP routes and found that the ‘ip routing’ command is not supported. I came across a document that stated “On switches running the LAN base feature, static routing on VLANs is supported only with Cisco IOS Release 12.2(58)SE and later.” So I have upgraded to 12.2(58)SE2, but ‘ip routing’ is still not a valid command.
The release notes state:“On the Cisco Catalyst 3560-X and 3750-X Series, it adds support for 16 static IPv4 routes in the LAN Base image.”
I have read other posts that talk about running the ‘sdm prefer routing’ command which I have done, but I am still unable to add any routes or run the ‘ip routing’ command.
I have an 1811 with several subnets connected to it.I recently installed a 3750x plant and want to bring my interior routing back to it.
All the routing is handled by the 1811 via secondary interfaces on vlan1?
I have 192 ports, and subnets show up on almost all of them. None of the ports are assigned to any specific vlans. Most ports have several subnets on them.
What is the best approach to getting the 3750x to handle the routing?
my company pay a switch 3750 X. WS-C3750X-24T-E. It uses IP services basically but I failed to configure InterVLAN routing. why interVLAN routing doesn't work on my switch?

How to know whether QoS work on the 3750X or not ? Is it correct about the config in scenario A ?
I have a one question. I am using Cat3750x-48 switch. Suddenly it has occurred following high CPU log message in Cat3750x-48 switch.
%SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 62%/0%, Top 3 processes(Pid/Util): 162/40%, 156/10%, 74/1%
What is meaning of PID 162 ?
There seems to be a lot of conflicting information on what can and can't stack together in the 3750X range.
I know that LAN Base can only stack with other LAN Base switches.
Can IP Base stack with IP services in 3750X? I have also heard that the 15.x.x IOS restricts mixed feature set stacks?
I know that Cisco recommends that all switches in a stack have the same IOS and feature set but having all IP Services in a stack can get too expensive.
I'm trying to review a QoS setup, and I'd like to make sure I fully understand the current setup before I change anything. I'm seeing output drops on two different queue-thresholds, but not sure how packets are making it to one of the queues.

I can find queue4-threshold3 in the mappings, but how are packets getting mapped to queue2-threshold1? The priority queue is disabled for this interface, so I'm not sure how this queue is dropping packets, according to the maps nothing is mapped to 02-01.
I am building a switch stack using 4 48 port 3750X switches that will also have the power stacked. If I install a single 715W power supply in each switch will the stack support 802.3af accross all 48 ports on each switch? My calculations are 48 ports x 15.4W which gives me almost 740W needed which is over hte 715W power supply. I was reading somewhere were it mentioned that in a powerstack additional power can be drawn from the stack. I know this will not work if you are trying to support power on all switches accross all ports but would it if say 2 of the 4 switches are needing to provide PoE accross all 48 ports? If I say we can only use 24 ports per switch for PoE that drops the power need down to 370W which I believe should work. Just trying to get a better understanding of PoE consumption. Would the best solution be to just add a second power supply to each switch?
