Hello all,
First post here; so I'm sorry if I am in the wrong thread..
I inherited a bunch of 5548's.
I have two 'stacks'; one stack of three(3) devices and another stack of two(2) devices.
The three stack is a VM cluster and the two stack is the Network/IDF.
On the IDF side I have this:
!
interface gigabitethernet1/0/43
description "Link to 5548 vmstk"
channel-group 6 mode auto
!
interface gigabitethernet1/0/44
description "Link to 5548 vmstk"
channel-group 6 mode auto
!
interface gigabitethernet1/0/45
description "Link to 5548 vmstk"
channel-group 6 mode auto
!
interface gigabitethernet1/0/46
description "Link to 5548 vmstk"
channel-group 6 mode auto
!
interface gigabitethernet1/0/47
description "Link to 5548 vmstk"
channel-group 6 mode auto
!
interface gigabitethernet1/0/48
description "Link to 5548 vmstk"
channel-group 6 mode auto
!
and in the vmstack I have this:
dl5548-vmstk# sh running-config interface gigabitethernet 1/0/47-48
interface gigabitethernet1/0/47
description "Link to 5548-stk"
channel-group 6 mode auto
!
interface gigabitethernet1/0/48
description "Link to 5548-stk"
channel-group 6 mode auto
!
dl5548-vmstk# sh running-config interface gigabitethernet 2/0/47-48
interface gigabitethernet2/0/47
description "Link to 5548-stk"
channel-group 6 mode auto
!
interface gigabitethernet2/0/48
description "Link to 5548-stk"
channel-group 6 mode auto
!
dl5548-vmstk# sh running-config interface gigabitethernet 3/0/47-48
interface gigabitethernet3/0/47
description "Link to 5548-stk"
channel-group 6 mode auto
!
interface gigabitethernet3/0/48
description "Link to 5548-stk"
channel-group 6 mode auto
!
I am looking for validation that this is a valid config..
vmstk gi1/0/47-48 goes to idfstk gi1/0/43-44
vmstk gi2/0/47-48 goes to idfstk gi1/0/45-46
vmstk gi3/0/47-48 goes to idfstk gi1/0/47-48
vmstk[1,2,3] are connected via hdmi stacking cables..
Should I have separate port-channels for each switch?
Is the same port channel on each vmstk switch a problem?
Is this an SMLT/IST problem? (http://en.wikipedia.org/wiki/Link_aggregation and http://en.wikipedia.org/wiki/IEEE_802.3ad)
sh interfaces counters port-channel 6
on both devices shows no errors..
Thanks in advance.
