i try to implement layer 2 qos in 2960. when i complete to configure the switch, i want to test the qos.PC1 conect to switch port 1,PC2 conect to switch port 2 . PC1 is source teminal. i use skydata.exe and FTP for the test.
when use the skydata ,the PC2 speed can reach 10mbps.when use the FTP , the PC2 only can reach 1.2mbps. why?

It doesnt like my password, but I have only set 1 password (king) on this switch. I've configured 3 other switches with SSH and had no problem. Been trouble shooting for awhile and It'd be great if I could have a 2nd set of eyes take a peek, Also, my running config is attached.

This port is connected to nexus 5 k.

View 3 Replies View RelatedI have a Catalyst 2960-S switch and a pre-standard IP Phone (Cisco 7960). When I connect the phone to the switch the switch recognizes the phone and supplies power. I would like to prevent this behaviour. ie. I would like to disable detection of pre-standard equipment. Is there a command I can issue on the 2960-S to do this? For example, on a switch from a different vendor I can issue the command: no power pre-std-detect to prevent it from detecting the 7960 phone, is there an equivalent command on the Catalyst 2960-S ?

Is there going to be a problem renumbering the stack as they physically sit or should I just configure the devices based on thier logical member numbers.

View 2 Replies View RelatedAt one of my sites, I have a 100mbit TLS. For this connection to work properly, the port on my end needs to be setup for 100mbit, full duplex.

I configure the necessary port for 100/full, and get 'notconnect' on that interface. I set the interface to auto/auto, and it negotiates at 100/half and causes collisions and packet loss.

we have currently a configuration with 3 bonded (link aggregation) channels, each delivering 1 Gb/s uplink, providing a total of 3 Gb/s uplink. Due to a recent network upgrade, we can now add more channels to the same group in order to have a total of 9 Gb/s uplink, meaning that we should bond toegether 9 channels. When we tried to change the old configuration in order to include six new channels to the bondend group we noticed 2 things: one channel was left in standby (blinking orange led),no increase in the uplink bandwidth semmed to happen,By looking around it looks like the channel group is limited to a maximum of 8 channels [*].

View 2 Replies View Related why the QoS deployment causes ports on 2960 switches to drop packets although there is no bandwidth contension? (output bit/second of the interface)packet drops at threshold 1, queue 2 ( queue 3 in config)
We are using Catalyst 2960 switches and are experiencing issues with QoS. After the QoS, we experience a lot of packet drops and it make the network slow. It appears that the slow performance relates to the egress queuing of each port.

We have quite a few 3560 & 2960 on our edge network - what I have been looking at was to access switches via web-interface i.e. web-browser. Only problem with this is it always gives you access on privilige level 15 which is not ideal as not all who we decide to give access to these switches will be admin and allowed to configure these swicthes - In the 3560/2960 data-sheet states:
"Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators"
Where as there is no mention of how to configure these two levels of Web-based management in the configuration guide.
I have 2 devices which need to communicate through Logical Link Control. Each device functions like this: they have a built in network switch that allows their internal components to communicate with TCP/IP which is then encapsulated inside LLC frames and sent out a special port. The LLC frames from each device all come from a single source MAC address and are broadcast out the network. The receiving deivce receives the LLC frames, unencapsulates the data and uses it directly.
Using it this way through a single 2960 (such that device 1 is connected to fa0/2 and device 2 is connected to fa0/23) with its own dedicated VLAN and no other traffic on the switch (all other ports shutdown), the two devices are unable to "connect". Using a SPAN session, I can clearly see them exchanging LLC frames, but if I connect my computer to the internal device switch and try to ping the other device through the LLC encapsulated link, I get anywhere from a 25% to 100% loss with response times between 2ms and 15ms.
When I connect the special ports of each device together directly with a straight through cat-5e cable, they can connect and I can successfully ping through the link with sub-millisecond response times. The same goes if I connect them through an old unmanaged Linksys switch. I have toggled everything on the 2960 I can think of, including STP, CDP, LLDP, storm control, keepalives, IGMP snooping, management interface VLAN1, and QoS. In general, the more of those that I turned off, the faster the ping responses became, but nothing seems to stop the data loss.
On first floor, I have two stack switches and each stack has got 4 switches. they all are working fine.Now the client would like to add one more stack on the 2nd floor. But the second floor switches are different when compared to the 1st floor switches.
can you have differnt IOS among different stacks. I knew in a stack we need all the switches should have same IOS version. But in between two stacks to communicate do we need same IOS or they can be on differnet IOS?
1st floor switches have 15.0 version and 2nd floor new switches has 12.2.58. Is this ok ?
1st floor switches are 3500 series ( Note: only one one Vlan 20 we are using on the both stack switches and we would like add same Vlan 20 on to the new stack)
2nd floor switches aew 2 catalyst 2960 switches.
Note: on the second floor switches one is 24 port switch and the other one is 48 port switch. so can i make them as a stack?
We have already done cabling from 1st floor to second floor. So no problem with that at all.
