From 7c91007e1e13b56a29236bd076891709eaa21754 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Wed, 3 Apr 2019 11:20:06 -0400 Subject: Make the loss / delay sim available as an output feature Add binary api and debug cli support. Rewrite for speed: enqueue vlib_buffer_t's to the wheel, instead of memcpy'ing data. Quad-loop the output feature / x-connect (interior) node. Prefetch wheel entries in the input node. Save packet-generator-based unit-test setup in extras/nsim. Simple config example: set nsim delay 20 ms bandwidth 1 gbit packet-size 1024 nsim output-feature enable-disable GigabitEthernet3/0/0 Change-Id: I852a32d4eb596e7e2aa1d9b30bf3b53525e39fd1 Signed-off-by: Dave Barach c --- extras/nsim/setup.nsim | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 extras/nsim/setup.nsim (limited to 'extras') diff --git a/extras/nsim/setup.nsim b/extras/nsim/setup.nsim new file mode 100644 index 00000000000..999b92a901a --- /dev/null +++ b/extras/nsim/setup.nsim @@ -0,0 +1,25 @@ +set term pag off + +loop cre + +set int ip address loop0 192.168.2.1/24 +set int state loop0 up +set nsim delay 20 ms bandwidth 1 gbit packet-size 128 +comment { add drop-fraction 0.8 or some such} +nsim output-feature enable-disable loop0 + +packet-generator new { + name icmp + limit 0 + size 128-128 + interface local0 + node ethernet-input + data { + IP4: 0001.dead.beef -> 0002.dead.beef + ICMP: 192.168.1.2 -> 192.168.2.2 + incrementing 30 + } +} + +set int ip address pg0 192.168.1.1/24 +set ip arp loop0 192.168.2.2 0003.dead.beef -- cgit 1.2.3-korg
