Oct 23, 2011

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 .

Cisco Switching/Routing :: 2960s Stack Port Shutdown

May 6, 2013

I have a single 2960s without stack module. The stack port has a status of down, however I'd like to disable it so that it does not generate a false alarm in my NMS. The documentation states that there should be a command "switch 1 stack port 1 disable" but the switch (running 15.0(2)SE2) doesn't seem to  be available. Is this a dcumentation bug or is the command not there at all?

Cisco Switching/Routing :: How To Monitor 3750 Stacking Port In LMS

May 24, 2012

I would like to ask about 3750 stacking and some Cat6 stuff...
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?

Cisco Firewall :: ASA 5520 - Solar Winds Real Time Interface / Monitor Through Put Of Port?

Jul 6, 2012

I have an ASA 5520 and I'm using Solar winds real time interface tool to monitor the through put of the port.  It seems I can never get it to use more than 100mb, where should I check?
I have run a sh int giga 0/1 and it shows the port is 1000mb full duplex and the I have also checked the other end where it plugs into the LAN and this also says the port is running at 1000mb full duplex.

when plugging a Cisco 7060 to the specific switch port it does not power on.  The inline power consumption is abnormally high compared to the other phones that are plugged in, maybe double the amount. 

non Poe devices work on the same port.
I used multiple cables and phones.

Cisco Switching/Routing :: Catalyst 2960S - Protected Port But Allow Specific MAC?

Nov 5, 2011

We are using catalyst 2960S Lan Base IOS on Radio towers. We just bought 50 Accest points, thas are GPS synchronized. Problem is the APs need to be connected on L2-mac betwen each other. But at this time we are using port isolation on each switch (tower) by protected port function to isolate clients from each other.
My question is, is possible to specifi a Mac addresses in specific vlan thats can comunicate betwen protected ports? On tower is one Master unit and others are slave. I thing there is only 1 dirrection comunication - from master to slave.

Cisco Switching/Routing :: 3750x Switch Port Rate Limit

Oct 8, 2012

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.

Cisco Switching/Routing :: Stacking 24 And 48 Port 3750X Switches Not Working?

Dec 11, 2012

We purchased a number of 3750X 48 and 24 port switches for the College Campus. Am finally getting around to getting them inserted on the network. Working with a WS-3750X-48PF-S and a WS-3750X-24P-L. Have them stacked with the 10Gb uplink on the 48 port switch. Have not been having fun.In the boot sequence, the switches recognize they are stacked, but as soon as they finish boot, I get the message on the 48 port switch: “Stack Port 1 Switch 1 has changed to state down.” Then “Stack Port 2 Switch1 has changed to state down.” Am noticing that I have a message preceding that: “Major version mismatch with stack neighbor.”The 48 port is running c3750e-universalk9-mz.150-1.SE3, HBOOT 12.2(53r)SE2.The 24 port is running c3750e-unversalk9-mz.122-55.SE3, HBOOT 12.2(53r)SE2Most of our 3750X and older switches are running 122-55 or 122.58 code. IP base or Universal. There is speculation that the problem is the 24 Port is Lan base, as the part number might indicate. (WS-C3750X-24-P-L.... I think that is the part number) and the 48 is IP base. Both switches are Universal, and my understanding is that they don't care about LAN or IP Base until you enable a function that falls in the IP Base domain. Then I have to call Cisco Licensing.For these switches, LAN Base is fine, based on the boot message, I feel the real problem is 122-55 versus 150-1 in the stack. So.. the question is: Do I downgrade the 48 port to match what we have in our environment, and what is on the 24 port switch. Or... Upgrade the 24 port switch to match the 48 port switch and have an installation that is not consistent with our environment? I do have two more edge closets to install with this purchase of 3750X 48 port switches.

Cisco Switching/Routing :: 3750X Port Channel Load Balancing Protocols

Jan 15, 2012

What I am attempting to achieve is to aggregate trunk ports out of a VMware server into a single logical connection to give as much bandwidth as possible, the switches are 3750X and are three stacked together with the server connections spread across the stack. What I am not sure about is if two port channel load balance protocols can happy co-exist on the switch, by default the switch is using MAC address load balancing and Vmware wants to use IP Source load balancing. As other trunks and channels exist on the switch I don't want to make a change that will affect the other live connections if changing this is a global setting and not local on the channel.

Cisco Switching/Routing :: 3750X - Adding Ports To Existing Port-channel

Jan 29, 2013

I need to tear down an existing port-channel on a 3750X running c3750e-universalk9-mz.150-1.SE3.bin. This port channel is currently down down. It has three ports in it that will be added one each to three existing port-channels, I am assuming as long as the "channel-group" command is exactly the same as it is on the three existing port-channels I should be ok just adding the new port. One point to note is that the three existing port-channels all have three ports so this will be adding the fourth port to each port-channel. I know after reading that it is a best practice for load balancing to use either 2, 4, or 8 ports for a port-channel. Also what is the command to see all ports that are in a port channel?

Cisco Switching/Routing :: 3560 - Trunk Port Recovery Time

Jul 10, 2012

I have a pair of 3560's configured with dot1q trunks between them carrying a number of VLANs.
Once deployed there will be a requirement for these physical trunks to be disconnected from time to time. Knowing that this is inevitable I am trying to minimise the period of time for the trunks to recover once the physical connectivity is reinstated.
All of the VLANs on the switches are configured for Spanning Tree Rapid PVST. Current time for the trunks/VLANs to come up is around the 4 second mark.

Cisco Switching/Routing :: 3750X / DHCP Server Not Handing Out Specific IPs

Apr 17, 2013

I have a DHCP server for a subnet that has only lightweight WAP's in it.  The DHCP server is running on the gateway for this subnet which is a 3750X 2 switch stack running 12.2(53r)se2.I have the following configured:

ip dhcp excluded-address
 ip dhcp pool DHCP-VL20
ease 3
The server hands out up to 18 IP addresses and no more, with 20 devices on the subnet.  Scanning the subnet with a 3rd party network management system I see the following IP's never get handed out or used: - 162 (manually excluded) - 168 - 176
and of course  2 IP's I have manually excluded, 11 IP's in all that wont get handed out.  It should only be 2 that don't get handed out.  I've double and triple checked the exclusion and thats the only one.  so I run a 'sh ip dhcp pool' and see this:
Pool DHCP-VL20 :
Utilization mark (high/low)    : 100 / 0
Subnet size (first/next)       : 0 / 0
Total addresses                : 30

[edit]I should also mention that "sh ip dhcp bind" does not show these randomly excluded IP's in use.  They also do not show up in any arp table I can find.I have looked all over the config and I cant find where these extra 9 addresses are being excluded. how to free up these 9 seemingly random exclusions?  Haven't issued a reload and I haven't deleted and rebuilt the DHCP server yet, production network.

Routers / Switches :: Rate Limit On Specific Port From Specific Range?

Jul 1, 2012

Is it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:

class ipv4 rate-limit-port-A1
match ip any
policy qos port-a1-ratelimit
class servers-to-be-slowed action rate-limit kbps 1000
interface A1 service-policy port-a1-ratelimit inI'm not sure about this.
