Cisco C3560G with 4x SGE2010P issues

[Lance Evans]

Hey Guys,

I have a Cisco Calayst C3560G core switch with 4 x SGE2010P Switches which are invidually linked/trunked via 2x CAT6 Cables for each SGE switch so im not stacking them. First problem is i cant seem to trunk/bond the 2 cables to the SGE LAGs i created, I can only use 1 cable per SGE switch. Yes the Core switch is configured correctly and have the proper Port Channel config (below is an example of a config) how do i get this working!?

I run POE Voip phones and PC's of 1 cable that is vlan'd on the phones, so each port on the SGE's are trunk'd

The other issue and more troublesome is that I have random reboots on all of the SGE's the LOGs tell me nothing! I cant seem to figure it out even had the units swapped out! Jumbo Frames are enabled but still happens even if disabled. Got some STP/RSTP settings but nothing helps.

Hello Lance,

What is the current mode of the SGE switch in the status page? Stacking or Standalone?

I would probably recommend calling into the support center at 1866-606-1866, but you could try to set the channel-group 1 mode to on instead of desirable.

What does the configuration look like on the SGE's. Is the LAG configured and what ports are memebers of the LAG?

configuration files might help for the SGE.

crying my eyes out, cant seem to figure this out! please help!!!

Hello Lance,

I am (or potentially will be) in a similar situation. Except in my case, the core switch is a 3750 and the access switches are SG300 series. To further complicate matters for myself, I have talked my boss into acquiring an additional 3750, in order to stack them. Anywho, for the time being, I have a spare 3750 and a spare SG300, so if you bare with me, I will attempt to create an etherchannel between the two.

I will report back shortly,

Albert

[Lance Evans]

Nice, should be an interesting setup. Please do let me know how it goes! Still battling myside.

Hi lance

I tried the following on my 3560

cisco WS-C3560-24PS (PowerPC405) processor (revision S0) with 131072K bytes of memory.

Processor board ID FDO1240X41U

Last reset from power-on

1 Virtual Ethernet interface

24 FastEthernet interfaces

2 Gigabit Ethernet interfaces

I am using my two gig ports for my channel group on the 3560.

I had switch port 1 of this switch connected to the expansion port of my CME  voice call controll unit.  It was suppied with two vlans , native vlan1 and tagged voice vlan100;

interface Port-channel1

switchport trunk encapsulation dot1q

switchport mode trunk

!

interface FastEthernet0/1

switchport trunk encapsulation dot1q

switchport mode trunk

switchport voice vlan 100

spanning-tree portfast

.

.

.

.

interface GigabitEthernet0/1

switchport trunk encapsulation dot1q

switchport mode trunk

channel-group 1 mode active

!

interface GigabitEthernet0/2

switchport trunk encapsulation dot1q

switchport mode trunk

channel-group 1 mode active

on my SGE2000, I am using ports 12 and 24 for connection to the 3560.

i set up the following and it seems to work;

console# sh run

interface port-channel 1

description to_3560

exit

interface port-channel 1

switchport mode trunk

exit

interface range ethernet g(1-11,13-23)

switchport mode trunk

exit

vlan database

vlan 100

exit

interface range ethernet g(1-11,13-23)

switchport trunk allowed vlan add 100

exit

interface port-channel 1

switchport trunk allowed vlan add 100

exit

interface vlan 100

name voice

exit

interface range ethernet g(12,24)

channel-group 1 mode auto

exit

interface vlan 1

ip address 192.168.10.254 255.255.255.0

exit

Must admit I plugged on IP phone onto switch port 1 of my SGE2000, but manually had to tell the phone it's admin vlan is 100.

regards Dave

Yip i had to set my voip phones manually as well!

So you have 2 cables actively trunked on 2 ports between your 3560 and sge!? Also i noticed u not using any STP nor RSTP settings on the SGE, I dont know if i can do that cause we do have 2 or 3 small switches around as well!
