Description Liang Zheng 2011-07-04 05:56:22 UTC

+++ This bug was initially created as a clone of Bug #707142 +++

Description of problem:
The bonding cannot change the LACPDU tx rate to request from 802.3ad partner when reset the parm:lacp_rate

Version-Release number of selected component (if applicable):
[root@hp-dl585g7-02 ~]# uname -r
2.6.32-131.0.15.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1.config switch to support 802.3ad
2.modprobe bonding mode=4 miimon=100 lacp_rate=1
3.ifconfig bond0 up
4.ifenslave bond0 eth1 eth7
5.tcpdump -p -e ether proto 0x8809 -i bond0 
  You can see request partner to transmit LACPDUs every 1 second
[root@hp-dl580g7-01 ~]# tcpdump -p ether proto 0x8809 -i bond0
tcpdump: WARNING: bond0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on bond0, link-type EN10MB (Ethernet), capture size 65535 bytes
03:58:42.302350 LACPv1, length 110
03:58:43.312393 LACPv1, length 110
03:58:44.312413 LACPv1, length 110
03:58:45.312478 LACPv1, length 110

5.ifconfig bond0 down
6.echo 0 > /sys/class/net/bond0/bonding/lacp_rate
  cat /proc/net/bonding/bond0
[root@hp-dl580g7-01 ~]# cat /proc/net/bonding/bond0 
Ethernet Channel Bonding Driver: v3.6.0 (September 26, 2009)

Bonding Mode: IEEE 802.3ad Dynamic link aggregation
Transmit Hash Policy: layer2 (0)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0

802.3ad info
LACP rate: slow         <====================
Aggregator selection policy (ad_select): stable
Active Aggregator Info:
	Aggregator ID: 2
	Number of ports: 1
	Actor Key: 33
	Partner Key: 0
	Partner Mac Address: 00:05:73:dd:9a:3c

7.ifconfig bond0 up 
  tcpdump -p -e ether proto 0x8809 -i bond0
  It still request partner to transmit LACPDUs every 1 second,
  didnot change to slow in every 30 second.

Detailed testing feedback is always welcomed.

Comment 6 Liang Zheng 2011-10-14 06:42:01 UTC

On kernel 2.6.18-287.el5
After change lacp_rate=slow ,bonding receive lacp packets every 30s.
So set verified
