[c-nsp] Configuring Ethernet Channel on a Cisco 7513

[Alexandra Alvarado]

Hello,

Thanks all for your help!

Is correct the bellow configuration?
Need I to create a port-channel iface in the switch?
No problem is I join two not sequential ports like 17 and 22 in a switch?
I use MSTP, No problem with the bellow configuration? How can I prevent a
loop caused for Ethernet channel?


Thanks

Alexandra Alvarado


Ethernet Channel Configuration

SWITCH CATALYST 3550
====================

interface FastEthernet0/17
 description FE9/1/0_Router_7513
 switchport access vlan 2
 channel-group 1 mode on	<<======
 switchport mode access
 switchport nonegotiate
 switchport port-security
 switchport port-security violation restrict
 switchport port-security mac-address 0002.0002.0002
 ip access-group 135 in
 shutdown
 duplex full
 speed 100
 no cdp enable
 spanning-tree bpduguard enable
 spanning-tree guard root
end

interface FastEthernet0/22
 description FE9/0/0_Router_7513
 switchport access vlan 2
 channel-group 1 mode on	<<======
 switchport mode access
 switchport nonegotiate
 switchport port-security

end


ROUTER CISCO 7513
=================

interface port-channel 1

correct.

Yes, you need to configure the neighboring switch as well, take a look
at
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/1214ea1/3550sc
g/swethchl.htm.
Please make sure to configure the switch with "mode on" (i.e. disable
PAgP/LACP) via "channel-group 1 mode on" since the router does not
support PAgP/LACP..
