View 4 RepliesI has a issue about etherchannel beetwen 02 Catalyst 6500 switch, i need your comment about it. if you had any similar experience:
1.- On Catalyst Switch 6500-1: I configured interface port-channel 4 and associated it to G6/29 and G6/30 interface Port-channel4description IUU1_Gn1_HLIMSGSN01_Port_channel_6_29_6_30switchportswitchport trunk encapsulation dot1qswitchport trunk allowed vlan 406,408switchport mode trunkswitchport nonegotiatelogging event link-statusload-interval 30mls qos vlan-basedmls qos trust dscp!
2.- On Catalyst Switch 6500-2: I configured interface port-channel 4 and associated it to G6/29 and G6/30

switchport trunk allowed vlan 407,409
[code]....
and i see output "show interface Po4A" up up on switch-1, "show interface Po4B" up up on switch-2
5.- In the show running-config not appear configured Po4A and Po4B. it only show on outputs
6.- Po4A and Po4 was not configured on neither switches, my question is why appear Po4A and Po4B on switch-1 and switch-2 respectively? and why Po4 appear in down down.
7.- I solved this issue by shutdown and not shutdown to the interfaces on both routers, currently all is OK.
we have cisco 6500 series switch and configured port channel on both switches with 2 gig interfaces on both switches.
When we enable the port channel mode to as desirable to the interfaces on both side and applied the port channel to physical interfaces switch will go down and if we remove on any one side switch will come up. we have enabled globally the following commands. [code]
how my switches are configured, a cisco 3750 and a cisco 4506.[code] i can ping the gateway from the 3750 however cannot get anything past that or enything to it.

View 1 Replies View RelatedI set up a port-channel trunk between a acess switch 3750 ( int gi2/0/1 and gi2/0/2) and Core 6509( int gi7/11 and gi7/12).
On the both the 3750& 6509 I configured:
interface Port-channel15
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 100,103
switchport mode trunk
But the ports on the core g7/11 and g7/12 keep shutdown and when I do show interfaces port-channel 15, it show the interface is shutdown.
I am building a new network and intended on using the min-link feature on my port-channels between a 3750-X series switch and Nexus 4k.
However reading further into this it seems this feature is only supported on higher end models. I cannot find any reference to the min-links feature in the 3750-X configuration guide. Is this an available feature?
The 3750-X model is WS-C3750X-24T-L running IOS 12.2(55)SE3 IP Services
My thoughts is that the is only an LACP supported feature so I may not see the command until I have entered an LACP specific command on the port-channel but unfortunately I do not have a 3750X to verify this on at present.
We have a switch that, when configuring auto qos on and edge port facing video equipment, the upstream port channel drops. I was wondering if no auto qos would have to be configured on the member ports of the port channel prior to enabling auto qos on any other ports.
View 2 Replies View Relatedhow to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
3750 Config:
interface Port-channel2
!
interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100
[code]....
Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.
I have a customer that would like a 40Gb port-channel between two 3750-x switch stacks. When I try to activate four 10Gb ports in the channel, they go into error-disable. However, I am able to create a 20Gb port-channel without issue. I have had my configurations verified to Cisco best practice.
Is there a limitation on the amount of throughput that the 3750-x can handle? According to the data sheet the 3750X-48T can handle 101.2mpps, based on two 10Gb uplinks so if my math is correct then a stack of two 3750X-48T should be able to handle 202.4mpps.

I am testing rogue on wire using 5508 WLC and , I have a dedicated AP configured as rogue detector and configured the switch port where the Rogue detector is connected as trunk. I have plugged in an autonomous AP with open authentication to the same switch so that it can act as a rogue. On the WLC, I can see that Autonomous AP as rogue on Wire. But along with that I am seeing another AP as rogue on wire, even though i have plugged in only one Autonomous AP to the switch.

We have QoS configured throughout the company, but the standard config we have applied across the 3750 switches only includes the below: We have IP phones (not cisco) attached that are marking with EF, and the PC is an untrusted end device (so needs to be by default marked as zero).Is the above enough to trust VOIP DSCP EF without resetting it to DSCP 0, or do I also need to add a trust line (i.e.: mls qos trust dscp)?

We have a cisco 3750-48 port switch.We have a few SVI's configured and some static routes configured.I had created a new interface vlan and gave it an IP. I can ping the gateway.
Now I want to add a static route to go out that interface.when I add: ip route 10.x.x.x 255.255.255.0 10.52.10.1
it eccepts it (no errors) But, it does not show in the routing table nor in the config? How to add the static route to go out that vlan interface.
Any method of forcing a non connected switch port LED to blink for a certain number of times regardless if there is anything connected.The purpose of this is we have remote 3750 switch stacks and quite often have to tell non technical staff to patch to a certain port. It would be much easier if we could say "Connect it to the empty port which just started blinking orange" as the port numbers are difficult for them to see in these locations.A similar feature is available in the ethtool package for linux which makes it really easy for identifying ports on servers. It would be great if a similar feature is available on Cisco switches.

We 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?
We need to change the Channel-group settings in 3750 switch from Mode ON to Mode Active. We have tried once by removing the physical interfaces from the port-channel group but we lost the connectivity to the secondary switch. Any step by step procedure without losing the connectivity between switches.

View 4 Replies View RelatedI have two Cisco 4506's running cat4500-ipbase-mz.122-50.SG3.bin. Periodically, when attaching a new workstation to these switches the Mac Address of the device disappears off the port when the device is connected or the port is configured. The only way to correct the issue is to do a hardware reset on the blade or reboot the switch. After resetting the blade or rebooting the switch the devices will start showing up on the port and connect. This does not effect devices that are already connected to the switch, just newly added devices
Both switches are populated with WS-X4148-RJ45, WS-X4148-RJ45V and WS-X4248-RJ45V blades. It doesn't matter which blade the new device is being connected to. I believe that this may be a "Bug" but have been unable to locate one.
I configured port security on my 2960 switches with the following commands: [code]
The problem is that when I should change someone's PC, first I disable port-secirity, then I clear all the mac addresses learned on the interface, then I plug the new PC and enable port-security. The new PC couldn't connect to the network and it's mac address has not be learned on the interface. Why?Which commands should I use to clear an old mac address and enable port-security with the new mac address.
