I'm trying to configure Etherchannel on AIX 5.3 and I'm having some problems. I am aggregating both of the onboard NIC's (ent0 and ent1) into a new adapter ent2 for failover reasons obviously. At first I was experiencing a problem where about 50% of all my packets would be dropped. Then after... (4 Replies)
I have 1 AIX server, 4 dual ported fiber attached ethernet cards and 4 VLANS coming in. Is it possible to present those 8 ports as 1 IP address using etherchannel? Thanks. (5 Replies)
I have one p5 server, no lpar, 2 physical network adapter, bundle as one EtherChannel. The two 2 physical network adapter connect to 2 network switches.
How to make this as a redundancy config?
Current is if one physical network adapter down, the seond one will go through the network. but if... (2 Replies)
I have few AIX servers in my data center, which have their EtherChannel configured to have a fat pipe (active/active) and a nagios server to monitor the server uptimes. Nagios server pings every server in the data center and we have pretty much every known unix flavor in this data center. When... (3 Replies)
Hi,
I have a AIX5.3 P6-520 with 8x1Gb Ethernet ports with possible connections to 2 CISCO 2960 switches.
I can create 8023ad Etherchannels which work correctly with the switches (I have set up for LACP passive and a valid channels)
But can create 2x 8023ad 4Gb Etherchannels with no backups.... (2 Replies)
hi guys,
i need to develop following setup for a customer:
high availability oracle database on aix7 and linux in 2 different LPAR using dual ps700 blande a ds3400 and HMC.
the question is, it is possible to have automatic vioc failover(aix,linux) when for example 1 vios goes down?

Hi Guys,
I am trying to test an etherchannel failover and switchback.
I did failover from primary to backup adapter, but now I am not able to switch it back to primary.

Hi,
I'm a newbie to PowerVM and LPARs ( I work with VmWare and Oracle VM Server for Sparc) .recently we purchased an 8202-e4b server, with two enclosures for add'l disk capacity. it is licensed for PowerVM standard,came preloaded as such, AIX 7.1.
I've set up HMC v8.2, and run it through a VM on... (30 Replies)
Hello,
After installing on P6 which is POWERVM IVM VIOS enabled (VET CODE D21C77ACD9229817CA1F00002C10004164 )

pvctxctl
PVCTXCTL(8) BSD System Manager's Manual PVCTXCTL(8)NAME
pvctxctl -- display or control ATM PVC transmitter parameters
SYNOPSIS
pvctxctl interface [[vpi:]vci]
pvctxctl interface [vpi:]vci [-n] [-b max-bandwidth] [-j [vpi:]vci] [-p pcr]
DESCRIPTION
pvctxctl displays or controls the shaper parameters of an ATM VC. When a shaper value is specified, pvctxctl sets a shaper to an ATM VC.
pvctxctl works for a PVC sub interface pvc(4) as well as a real ATM interface en(4).
For a real ATM interface, the specified VC should be assigned beforehand by route(8).
For a sub interface, pvctxctl assigns the specified VC to the sub interface. If another VC is already assigned to the sub interface, the old
VC is invalidated.
Availability of shapers, the number of hardware shaper channels, and accuracy of shaping are all device dependent. For example, ENI Midway
chip has 8 shaper channels but the driver reserves one for non-shaping VCs.
The options are as follows:
interface The interface parameter is a string of the form ``name unit'', for example, ``en0''.
[vpi:]vci The VC number to which the shaper is assigned. When the VPI number is omitted, VPI number 0 is assumed. For example, to assign
a shaper to VPI=0 and VCI=201, the following forms can be used: "201", "0xc9", "0:201", "0:0xc9".
-b max-bandwidth
The PCR parameter can be specified also in ``bits per second''. The rate is the rate of AAL5 frame and the PCR is calculated by
the following form:
PCR = max-bandwidth / 8 / 48
``K'' and ``M'' can be used as a short hand of ``000'' and ``000000'' respectively. For example, ``45M'' means ``45Mbps'' or PCR
value ``117187''.
-j [vpi:]vci
The join parameter is intended for VP shaping. The VC shaper channel is shared with the existing VC, which means the sum of the
cell rates never exceeds the maximum PCR among the shared VCs. On the other hand, when the shaper channel is not shared, the sum
of the cell rates could be the sum of the PCRs.
For example, if two VCs (say 201 and 202) share a 45Mbps VP, use:
# pvctxctl en0 201 -b 45M
# pvctxctl en0 202 -b 45M -j 201
-n This parameter is only for a sub interface. Use NULL encapsulation instead of LLC/SNAP.
-p pcr The PCR (Peak Cell Rate) parameter specifies the peak cell rate in "cells per second". If PCR value "0" is specified, no shaper
is assigned, which means cells are sent at full-speed of the link. If PCR value ``-1'' is specified, the corresponding VC is
invalidated.
SEE ALSO en(4), ifconfig(8), pvcsif(8), route(8)BUGS
A real ATM interface and a sub interface require different sequences to set a shaper. For example, to assign a 45Mbps shaper to VC 201
(0xc9) of en0:
# ifconfig en0 10.0.0.1
# route add -iface 10.0.0.2 -link en0:3.0.0.c9
# pvctxctl en0 0xc9 -b 45M
For a shadow interface,
# pvcsif en0 # creates pvc0
# ifconfig pvc0 10.0.0.1 10.0.0.2
# pvctxctl pvc0 201 -b 45M
