Pppoe over port-channels on ios xe

has the ability to do pppoe and QinQ over port-channels been added to IOS XE? as of 2.6 it was not but I cannot find any documentation on 3.1-3.3 to say that it has or hasn't
Does any one use a asr1000 as a BRAS and if so how do you handle redundancy in case of the loss of a primary interface handling your pppoe sessions?

Hi Artyom,
Try removing "ipv6 nd managed-config-flag" and see if it helps.

MPLS-TE over Port-channel on 7206

Hi Guys,
I need an information: on a 7206vxr (ios 15.2S) I tried to configure an mpls-te over an etherchannel link but it doesn't seems to work (the TE tunnel never go up and the "show mpls traffic-eng tunnel tunnel 0 det" show the reason as "invalid path" but I guarantee that it's absolutely valid).
I tried to search into feature navigator but I don't found any of that: It figure out as 7206 don't support it, it's right?
Thanks in advance
Giulio

Hi Giulio, can you please confirm that to me?
In the IOS feature navigator the feature "MPLS TE - Bundled interface support (EtherChannel and MLP)" seems to be available only in 7600 platform and not in 7200 series. And with 7200 series I have had some difficulty with MPLS TE in a port-channel interface.
Thankyou

Xconnect 20Gb Port-channel over MPLS Possible?

Can anybody confirm if you can establish an Xconnect between two 20Gb port-channels (2x 10Gig bundle). The core is 40Gig and running MPLS. We have many gigabit pseudowires running over it already.
Our intention is to terminate 10Gig server traffic on 4900M's and then have a 20Gb Port channel trunk link into a 6500 (which is part of the MPLS cloud). We would then issue the xconnect directly on the 20Gig port channel in order to traverse the MPLS Core.
Has anyone configured this before? Are there any caveats to watch out for? What sort of performance hit (if any does) xconnect functionality have on 10Gig Traffic.

Hi,
Yes it's supported but test it first (as always ;-) )

Multiple vsan traffic over single port-channel

Hi -
Scenario - 2 interface uplink (port-channel - Po10 ) from NetApp FAS-A to N5548-A & B. Po10 is currently configured with vPC10 and vFC10 at N5k end. single vfc currently mapped with a single vsan (vfc10 with vsan 1011).
Q - Is it possible to make the Port-channel to pass multiple vsan (vsan 1011 & 1012). If yes, then how (over same vfc or by separate vfc on same port-channel)
Subhankar

This router’s capability is only limited and dependent on the services that your ISP has given or allowed for you to use. I think it really has to be a one is to one configuration, not only with this router because I haven’t noticed any router that has this feature so far. This is really another idea for Linksys can work on.

IOS to NXOS VPC PORT CHANNEL

Hello
I have a pair of Nexus 5K's in a VPC domain and some 2960's as VPC members, with a port channel to the domain.
Topology is as follows:
5K1 and 5K2 in VPC domain
VPC from 5K1 and 5K2 to 2960
2960 has gi0/1 and gi0/2 in 1 port channel
gi0/1 to 5k1, gi0/2 to 5k2
I know that what I am going to ask may be totally against the purpose of VPC, but, I am looking for a way to favour gi0/1 for traffic, rather than load balancing over gi0/1 and gi0/2. The reaon for this is that I would like to benefit from the lack of loop that VPC provides, but would also like to have a primary and secondary link as the majority of traffic should actually go via 5K1, rather than 5K2.
Any suggestions welcome.
Many thanks in advance
Anthony

Hi Anthony,
The Cisco NX-OS software load balances traffic across all operational interfaces in a portchannel by hashing the addresses in the frame to a numerical value that selects one of the links in the channel. Port channels provide load balancing by default. Port-channel load-balancing uses MAC addresses, IP addresses, or Layer 4 port numbers to select the link. Port-channel load balancing uses either source or destination addresses or ports, or both source and destination addresses or ports.
You can configure the load-balancing mode to apply to all port channels that are configured on the entire device or on specified modules. The per-module configuration takes precedence over the load-balancing configuration for the entire device. You can configure one load-balancing mode for the entire device, a different mode for specified
modules, and another mode for the other specified modules. You cannot configure the load-balancing method per port channel.
You can configure the type of load-balancing algorithm used. You can choose the load-balancing algorithm that determines which member port to select for egress traffic by looking at the fields in the frame.
Note: The default load-balancing mode for Layer 3 interfaces is the source and destination IP address, and the default load-balancing mode for non-IP interfaces is the source and destination MAC address.
From the config mode you can try different load-balacing method ,
port-channel load-balance {dest-ip-port | dest-ip-port-vlan |
destination-ip-vlan | destination-mac | destination-port | source-dest-ip-port | source-dest-ip-port-vlan | source-dest-ip-vlan | source-dest-mac | source-dest-port | source-ip-port | source-ip-port-vlan | source-ip-vlan | source-mac | source-port} [module-number]
To Summarize: I cannot say which port would be selected, it purely depends on type of frame you are sending with the combination of the load-balance method.
After tweaking you can also know from the command which link the traffic is taking,
NEXUS2-SPAN# show port-channel load-balance forwarding-path interface port-channel 71 src-ip 1.1.1.1 dst-ip 2.2.2.2 vlan 51 module 2
Module 2: Missing params will be substituted by 0's.
Load-balance Algorithm: src-dst ip-l4port
RBH: 0xb0 Outgoing port id: Ethernet8/8
we can also try tweaking the same load-balancing on the 2960 also. It purely depends on the load-balancing algorithm. Below is for 2960 Load-balancing tweaking,
http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_53_se/configuration/guide/swethchl.html
Even after doing this i wouldnt say 100% it would select one link.
Hope this helps!
Thanks,
Richard.

Port Channel over L2 MPLS links

Hello.
I was hoping that someone could over some suggestions on best practice or recommendations for configuring port channel to bundle to layer 2 MPLS links that we have.
We have racks in two geographically separated data centres, each rack has a stack of Cisco 3850 switches, and there are two 100Mbps layer 2 connections linking these stacks together. The links are provided by our supplier and runs over their core network (I can get more info on their setup if need be).
I had initially just configured a simple port channel bundling the two ports on "Switch A", and the same on "Switch B". However I have since noticed that one of the ports was put into error disabled state, and I have my doubts that we ever had 200Mbps throughput over the portchannel.
The logs showed:
UDLD-4-UDLD_PORT_DISABLED: UDLD disabled interface Gix/x/x, aggressive mode failure detected
%PM-4-ERR_DISABLE: udld error detected on Gix/x/x, putting Gix/x/x in err-disable state
How I understand is that one of ports recieved an unexpected (or incorrect) BPDU packet, and shut the port down as part of spanning tree process to stop a loop forming.
For the time being I have removed the port channel config and re-opened all the ports, so I believe one of the ports is now in blocking state.
Whilst redundancy for these links is great, ideally I would like to have the links bundled so I also get the benefit of higher throughput.
Any thoughts are greatly appreciated.
Thank you

Hi,
Thank you for your reply and suggestions. I have been reading up on layer 2 protocol tunnelling and I'm not sure if this will work for us. According to these guidelines for the catalyst 3550 (http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3550/software/release/12-1_19_ea1/configuration/guide/3550scg/swtunnel.html#wp1006657) it states:
•If you enable PAgP or LACP tunneling, we recommend that you also enable UDLD on the interface for faster link-failure detection.
•Tunneling is not supported on trunk ports. If you enter the l2protocol-tunnel interface configuration command on a trunk port, the command is accepted, but Layer 2 tunneling does not take affect unless you change the port to a tunnel port or an access port.
•EtherChannel port groups are compatible with tunnel ports when the 802.1Q configuration is consistent within an EtherChannel port group.
(maybe its a different and is supported on 3850's)
Also, I cant use layer 3 over this link as I am looking to extend VLANs over the link so devices and virtual machines in each of the datacentre are in the same subnet and broadcast domain.
I will speak with the supplier to see what they are willing to do.
Thanks again.

UCS - san-port-channel over vpc

Hi,
I'm hoping someone can help out with this,
I have a setup with 2 Nexus 5548's connected over a vpc peer link and a keepalive, These two nexus switch's have a standard VPC connection to an upstream 6500. this is working fine,
Then there are multiple native FC connections from the 5548's to 6248's. I know there is the option to configure FC port-channel's on the UCS 2.0 but is it possible to put fc interfaces of the nexus 5548 into a san port-channel across a vpc between the the nexus 5548's.
so for example, can i port-channel the following across a vpc or is a san port-channel restricted to ports on the same nexus switch only.
Fabric A fc1/31 & fc1/32 uplinked to -> NX5K-1 Port fc1/31 & NX5K-2 Port fc1/32 (san port-channel 10 over a VPC)
Fabric B fc1/31 & fc1/32 uplinked to -> NX5K-1 Port fc1/32 & NXFK-2 Port fc1/31 (san port-channel 11 over a VPC)
Thanks,
Ray.

This is not possible. Vpc is layer 2 only ethernet port channel. San port channel cannot be built accross vpc

Right way of configuring higher MTU over a Port Channel

Hi guys,
I have a running critical Port-Channel between two locations.
Here's the config
SW1:
interface Port-channel2
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
interface GigabitEthernet1/45
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode active
end
interface GigabitEthernet1/46
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode active
end
SW2
interface GigabitEthernet1/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode passive
end
interface GigabitEthernet1/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode passive
end
interface Port-channel2
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
Now I need to increase the MTU from default value to 9198. What the right way to do it and avoid any connectivity loss, PortChannel restart.
Does it matter what switch I start first?
Thanks!
L.E. both SW are WS-C4948

Hi,
Because you are using layer 2 interfaces - there is no fragmentation support at layer 2, and interfaces receiving frames which have an unsupported size will be dropped.
I think the best way for you to proceed is to lab this up; and verify what happens - it may be that you need to make changes on switches at either end of the channel within a very short time frame to prevent too large an outage.
When you are ready to maike your change - think the best way to do this is to use the interface range command, and apply the 'mtu' command to all the interfaces in this range. I don't think it matters which switch you apply this change to first, and I don't believe if you are hinting at the 802.3ad (controlled by system-priority) decision maker, that it makes any difference.

So I have the following questions about verion 9:
1. Can I still use port-channels on a sigle ASA?
2. Should I replace port-channel by lacp command on a sigle ASA?
3. Does lacp command can be used only on clusters ?
Att.,
Rosa

The following is documented in the config guide for both 8.4 and 9.0:
•You cannot use interfaces on the 4GE SSM, including the integrated 4GE SSM in slot 1 on the ASA 5550, as part of an EtherChannel.
So, even with 8.4 it was probably never meant to work.

Does Solaris 10 support cisco Virtual Port Channels over IP?

Does anyone know if Solaris 10 support cisco Virtual Port Channels open IP?

Hi user11114413,
The issue you are seeing actually has little to do with VIP, and more to do with there being multiple IP addresses for us to choose from on your box. For such multi-IP boxes, you'll want to tell us the IP to use, and in your case you want to tell as a VIP. This can be done either by editing your operational configuration file, and including an <address> element within the <unicast-listener> element, or via the tangosol.coherence.localhost system property. For example:
<unicast-listener>
    <well-known-addresses>
        <socket-address id="1">
            <address>1.2.3.260</address> 
            <port>8088</port>
        </socket-address>
    </well-known-addresses>
    <address>1.2.3.260</address> 
    <port>8088</port>
</unicast-listener>or
java ... -Dtangosol.coherence.localhost=1.2.3.260If you are using the same operational configuration on all nodes in your cluster then the system property approach is likely preferable, and would only be necessary on the two machines sharing the VIP.
As for using VIP or an extended WKA list, the choice is yours, either will work. If you do go the VIP route, it would obviously be a very bad idea to simultaneously use the same VIP and port at the same time from the two machines.
thanks,

Port-channel issue over Ciena DWDM

Hi all,
I'm currently working on an issue encountered on a DC.
We currently use 2 3750 stacks (1 in each DC), connected with a Po.
We use dark fiber between each DC, so we have a Ciena DWDM transponder on each side.
The problem is that, if we have an issue on the inter-DC fiber, the Ciena interface on the 3750 side is still up. Using LACP on the Po, the issue can be detected in about 3 X 30 sec = 90 sec.
Before the issue is detected by LACP, the impacted port-channel interface is still used by the Po, which can cause big issues.
I thought use an EEM applet in order to monitor the CDP neighbor on each interface, and exclude the interface from the Po till the CDP neighbor is down, but the CDP timers are even bigger (180 sec hold-time).
Is there any way to address this problem, other than UDLD ?
In our others DC, we have two NX7K on each side, and we are able to use LACP with fast-rate, but this is not available on 3750...
Thank you very much !

the best way to use pair of transponders on each side in protection group.

HSRP over L3 port-channel, switches do not ping each other

Hello guys,
I have a L3 port-channel between 2 gigabit ethernet interfaces (one per switch Catalyst 6509), towards two giga interfaces in another two Catalyst 6509 in the other end. The port-channel is configured as follows in one of the ends (the first pair of 6509):
interface GigabitEthernet3/37
description Conexion
no ip address
channel-group 8 mode on
interface GigabitEthernet3/38
description Conexion
no ip address
channel-group 8 mode on
For each Catalyst 6509, the port-channel 8 has a HSRP group, 254. In one of the Catalyst (Central-1) the IP assigned is 192.168.254.253/24 and in the other (Central-2), 192.168.254.254/24. Here is the conf for one Catalyst 6509 (Central-1):
interface Port-channel8
description CENTRALES
ip address 192.168.254.253 255.255.255.0
no ip redirects
no ip unreachables
no ip proxy-arp
no ip route-cache
load-interval 30
standby delay minimum 20 reload 300
standby preempt delay minimum 120
standby 254 ip 192.168.254.254
standby 254 timers 1 3
As you can see, HSRP group 254 is defined and it is answering from L3, (from any host or switch, for the 3 IPs), but my doubt is about the HSRP behaviour between both Catalyst. They can't find which one is the master and in fact, they can't ping each other. The status of the group defined for po 8 is:
CENTRAL-1#sh standby port-channel 8
Port-channel8 - Group 254
Local state is Active, priority 100
Hellotime 1 sec, holdtime 3 sec
Next hello sent in 0.865
Virtual IP address is 192.168.254.254 configured
Active router is local
Standby router is unknown
Virtual mac address is 0000.0c07.acfe
5 state changes, last state change 2w3d
IP redundancy name is "hsrp-Po8-254" (default)
CENTRAL-2#sh standby port-channel 8
Port-channel8 - Group 254
Local state is Active, priority 110
Hellotime 1 sec, holdtime 3 sec
Next hello sent in 0.645
Virtual IP address is 192.168.254.254 configured
Active router is local
Standby router is unknown
Virtual mac address is 0000.0c07.acfe
5 state changes, last state change 6w1d
IP redundancy name is "hsrp-Po8-254" (default)
A "sh standby br" shows each switch considers itself the master and does not know the standby.
The thing is both switches have not an interface to connect L3 from network 192.168.254.0/24 directly. I mean, they only have one interface connected to the other end of the etherchannel, but not between them. Is this the reason why they can't ping each other, and consequently, they can't properly use HSRP group?
Could you tell me which could be a solution to this issue? I can't guess what can be done since the physical interfaces gi3/37 and gi3/38 exist and I think no any other interface should be configured in this network (192.168.254.0/24).
Thank you very much in advance.

Hello Jon,
Thank you very much for your answer. For the 3 possibilities, I answer you:
1) The pair are interconnected with a L2 trunk but the thing is this network, 192.168.254.0/24, is not associated to a vlan, but to a L3 etherchannel, so there is no way to associate it to a VLAN, am I right?
2) The other end of connections I think is configured at L3 too.
3) I am pending to know about the other end, but I think it is L3 too.
Anyway, although you have been very clear, try to imagine just 2 switches connected towards another 2 by one interface per each:
Central-1: gi3/37 ---> Ext1: gi1/20
Central-2: gi3/38 ---> Ext2: gi1/30
If etherchannel from Central is L3, I do not know how to include this traffic in vlan 2....
Well, I keep on thinking. Thank you very much.

Storm Control on Port-Channel Interfaces (6500 platform)

Hello.
I cannot find it anywhere in the documentation for the Cisco 6500 platform (IOS). The question is this: When calculating the percentage of broadcast passing through a Port-Channel interface, which total bandwidth figure is used by the switch? For example:
a. If we have a bundle of 4 Gig interfaces in a PortChannel with Storm-Control applied, the threshold will be calculated over 4Gb/s or 1Gb/s?
b. If the same PortChannel for some reason loses 2 of the uplinks in the Bundle, will the calculation be made over 4Gb/s, 2Gb/s or 1Gb/s?
Thanks!

Hi Leo,
I can't find any reference to this at the moment, but my thoughts are that it will be based on a single member port of the port-channel.
Remember that a port-channel is logically a single link and so a broadcast is only sent on one of the links of the port-channel and not all of them. The decision as to which link is used will be the same as for any other frame i.e., the broadcast address is used within the hashing calculation to choose the physical port.
If the storm-control values are determined based upon the aggregate bandwidth, and changes as links are added/removed from the agregate, then the suppression threshold values for link carrying the broadcasts is never going to be correct.

How to configure a port channel with VLAN trunking (and make it work..)

We're trying to configure a port channel group with trunked ports to connect a NetApp HA pair. We want to create two data LIFs and connect them to the switch stack. We are trying to create 2 data lifs, one for cifs and one for nfs that are on different vlans.
We want the same ports to be able to allow multiple vlans to communicate. (trunked)
These data lifs should be able to fail over to different nodes in the HA pair and still be able to communicate on the network.
What this means is that we have to connect 4 ports each for each node in the NetApp HA Pair to the switches and create a port channel of some type that allows for trunked vlans. When we configure the ports, the configuration is as follows (below):
We are only able to configure an IP on one of the vlans.
When we configure an IP from another vlan for the data lif, it does not respond to a ping.
Does anyone have any idea what I'm doing wrong on the Cisco switch?
