Possible to configure multichassis port-channel between a VSS and 3750X (Port-channel not in the same switch on the 3750X stack). I got it using LACP but I need Pagp to get VSL redundancy “dual-active detection pagp trust channel-group 1”. I am using the last VSS IOS version 15.0(1)SY. I can’t get the option “switch 1 preempt”, has it changed with other option?
View 2 RepliesI have an 891W that I initially configured using CCP Express (2.5). So it has a WAN IP set, and through CCP Express I had enabled via the checkboxes the various default settings for security. This includes zone-based firewall. I then added a number of NAT entries in the setup wizard.
What never occured to me at the time was that I should have added entries that allow for remote access. So it seems I've locked myself out of accessing the router via the WAN interface even though I know it's IP. I'm sure it's just a matter of adding port exceptions for SSH and/or whatever port(s) CCP uses.
So I"m wondering what the proces woudl be. In the IOS while showing the running config., I see pages and pages of class-map stuff which at present I don't know enough about to risk editing anything directly. But maybe I don't have to? What would be the best way to, for example, enable SSH access through the firewall? I already have transport input ssh set on the interface itself so I believe it's ready to allow the connection, just that I can't get to it via WAN int. so I assume it's the firewall.
I have two stacks 3750X on two different sites with two links L_2_L, and I want to configure the port channel to aggregate the two links.
Site A Site B
3750X -A1 --------------------------------------( )--------------------------------------- 3750X -B1
( L-2-L )
3750X -A2 --------------------------------------( )--------------------------------------- 3750X -B2
Below the configuration that I have put the two stacks.
site A
interface Port-channel5

But the problem is only one link is Bundeled in channel group, see below

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.
View 2 Replies View RelatedI 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?
View 1 Replies View Relatedi have a VSS core that has 4 downstream links to 4 stacked switches. I connected each of the 4 links to different switch in the switch stack. I then created a port-channel that combines all the links from each switch. Is there any issues associated with this setup?
View 9 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

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.

View 1 Replies View RelatedI have 2 Cisco 6509 switches linked together via single Fibre as a trunk.I want to change this to a port channel where I will add another 3 fibre ports to the port channel but what order do I do this to minimise any disruption.
1-Configure PortChannel and add the 3 new ports, this will bring up the Port Channel but what effect will this have on traffic currently going over the single Trunk link? Will spanning tree go mad, how will switches react?
2-Convert existing Trunk link to Portchannel then add in new ports to PortChannel, I guess in doing this there will be a small hit on traffic as it changes to a port channel.

I 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 one 3825 router used as voice gateway. For redudancy, we want to connect it to two different switches which has STP and HSRP running. Can I create a port-channel with two Giga interfaces in 3825 and connect to two different switches? Should I configure port channel in switch with only one port in each port-channel? I know server can be connected to different switches with NIC teaming. I just want to mimic that kind of setup. I did one time for port-channel in 3825, but it was connected to a stacked 3750X. So it's different case now.

I am using 3560.IP rouitng is being turned off on this.Curious to know if I will create etherchannel or port channel.I think etherchannel.Correct me if I am wrong.On connecting switches I have vlan10,20,30 to be allowed.I am sure I need to allow these all vlan in 10,20,30 which are on the trunk port on each side switch.Post that will add channel-port lacp and make it in active mode.Is that correct.This way traffic will be load-balanced/aggregated on minimum 2 ports who are the part of this.

I need to know if I can use the redundant supervisor 10 Gb uplinks to form a layer-2 Port channel between the two 6500 switches as i do not want to use want to keep the port idle additionally I need more bandwidth between the two switches for my server farm?
I have 2 cisco 6500 in a VSS configuration , All of my Lan access switches are Stack switches and every Stack is connected to the VSS in a Port-channel so basically this is a loop free environment with no blocked ports .As a best practice I left STP in the Background (mstp)which enhanced cisco features to STP should I configure on the Aggregator (6500-VSS) and on the Access switches ?
Because of my topology I dont see the need in configuring most features like Uplink Fast and Backbone Fast but I have configured Loop Guard in addition to UDLD on the 6500 Aggregation Switches (on the port-channels).On the access ports I have configured portfast , bpduguard and guard root (seems a little pointless to configure the two...)
1.should I Leave UDLD on and get rid of LoopGuard and configure Guard root instead ? since LoopGuard cannot be configured with Guard Root.
2.should I configure GuardRoot on access ports if I already have BpduGuard on them ?
3.Is there anything I need to configure on the physicall interface or is everything configured on the port-channel since STP reguards port- channel as a single interface ?
