Junos Shaping 設定

Junos の Shaping 機能についてテストした際の備忘録です。スループット測定は iperf を使用しました。

iperf の準備

epel リポジトリインストール

# wget http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
# wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
# rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm

iperf インストール

# yum install -y iperf

iperf 起動（サーバ側：192.168.100.1）

# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------

スループット測定

Shaping 設定前

# iperf -c 192.168.100.1
------------------------------------------------------------
Client connecting to 192.168.100.1, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[  3] local 100.64.1.1 port 38985 connected with 192.168.100.1 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec   845 MBytes   708 Mbits/sec

Shaping(200Mbps)設定後

# iperf -c 192.168.100.1
------------------------------------------------------------
Client connecting to 192.168.100.1, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
