6509 Etherchanneling

[hobbes80]

I'm working on a 6509, I believe it is only Layer2
I'm creating an ether channel to connect to an EMC device that I don't think supports PAgP.

I've created the channel using:
channel-group 1 mode on

from the range of ports (2/1 - 4) that I wanted connected.

The groups say it is created and the EMC gear is showing the trunk up, but I cannot ping the device and I can't joing the port-channel group into the vlan, gives me the error "Command rejected: Po1 is not a switching port" I try to set switchport and receive "Command rejected: Not a Convertible Port"

If I just set each of the ports to individually be switchports and then add them to vlan 2, I can ping it, but I don't believe I'm getting the benefit then of the aggragated ports. Any ideas?
Thanks

The first question is what are you trying to do , etherchannelling and trunking are 2 different things . We need to answer that question first . Here is a page that might help , not knowing what the EMC gear supports etherchannel wise, does it support LACP etcc ... this might be a trial and error until you find the right combo . If the EMC device supports LACP it might be easier to set it up using that as that is supposed to be the IEEE standard for creating etherchannels between vendors .

Just one thing to check is to make sure all your ports in the etherchannel are in the same vlan , and the ports are setup as switchports . Type switchport , enter . then switch port access vlan XX . Also this is applicable on the EMC gear and the the ip addresses you are trying to ping obviously have to be in the same vlan if this is a strict layer 2 vlan with no trunking across it .

PAgP is not supported on non Cisco devices. As has been mentioned LACP is the way to go unless you require Manual configuration and operation.

If you are using multiple VLANs then you will need to enable trunking over the etherchannel.

Remember that both ends of an etherchannel must be identical. Check the Duplex and speed of both ends of the link.
Ensure that they are encapsulated correctly if using trunking (ie 802.1q).

What is the OS? Is it CATOS or IOS?


Reamin positive. The affect on those around you will amaze.

It is IOS. The Duplex and Speed at both ends are hard coded to 1000 full. The way it has been explained to me from EMC is that the Cisco side of the house handles the etherchannelling, which doesn't compute to me because it is my understanding that the devices have to work in unison to do so. PAgP is definitely not supported (get nasty error messages) and while LACP is supported, I have been told the configuration on the EMC side is a nightmare and barely stable at best.

right now the 4 ports I'm channeling together are all set:
1000 Full
switchport
switchport mode access
switchport access vlan 2

Adding them to a channel-group makes all those settings disappear. Then I can't re-add them, nor can I add them to the properties of the interface group.

so at this point, do I conf t, then enter the interface for the range (int range gi 2/1 - 4) and channel-group 1 mode on (on for Etherchannel), or do I have to configure a dot1q vlan or what?
Thanks for the help so far..
