Multitable Resources
- Tracy Yang (Unlicensed)
Description
From PicOS version 2.7.1, some new modifications have been made to the multitable feature with the addition of the "resource" feature. Different platforms have different resources.
(All platforms which support l2-l3-buffer-mode are as follows: as5712_54x, as6701_32x, as6712_32x, dcs7032q28, es4654bf, niagara2632xl, niagara2948_6xl, pronto5101, pronto5401, as4610_54p, as4610_54t, as4610_30p, as4610_30t)

First, user should enable the L2 and L3 mode. Then, use the command "ovs-appctl pica/show tables " to check the L2 and L3 max flows in the switch.
Example
Step 1: Add bridge and port
ovs-vsctl add-br br0 -- set bridge br0 datapath_type=pica8 ovs-vsctl add-port br0 te-1/1/77 vlan_mode=trunk tag=1 -- set Interface te-1/1/77 type=pica8 ovs-vsctl add-port br0 te-1/1/78 vlan_mode=trunk tag=1 -- set Interface te-1/1/78 type=pica8
Step 2: Enable L2 and L3 mode
ovs-vsctl set-l2-mode true ovs-vsctl set-l3-mode true
Step 3: Check the default resources
admin@PicOS-OVS$ovs-appctl pica/show tables Pica Tables Statistics: Pica Tables Max Limitation Current Used ----------------------------------------------------------------------- ICAP Table 2044 10 ECAP Table (null) (null) VCAP Table 512 0 L2 System Table 512 0 L2 FDB Table 32256 0 L3 Host Table 12000 IPv4(0),IPv6(0*2) L3 Route Table 12000 IPv4(0),IPv6(0*2) UDF Table (null) (null)
Step 4: Add L2 flows
ssun@dev-42:~/ryu/ryu/app$ ryu-manager simple_switch_13_ssun_buffer_mode5.py
for i in range(4797, 5195):
for k in ('0','1','2','3','4','5','6','7','8','9'):
for z in ('0','1','2','3','4','5','6','7','8','9'):
dl_dst="22:22:22:22:"+k+z+":22"
match=self.set_match(datapath, dl_dst=dl_dst, vlan_vid=i)
output_port=78
actions=self.set_action(datapath, out_port=output_port)
self.add_flow(datapath, 251, 32768, match, actions)
Step 5: Check max L2 flow members
admin@PicOS-OVS$ovs-ofctl dump-flows br0|grep -c "table=251" 32256 admin@PicOS-OVS$ovs-appctl pica/show tables Pica Tables Statistics: Pica Tables Max Limitation Current Used ----------------------------------------------------------------------- ICAP Table 2044 8 ECAP Table (null) (null) VCAP Table 512 0 L2 System Table 512 0 L2 FDB Table 32256 32256 L3 Host Table 12000 IPv4(0),IPv6(0*2) L3 Route Table 12000 IPv4(0),IPv6(0*2) UDF Table (null) (null)
Step 6: Delete L2 flows and add ipv4 net route (ipv4 l3 host ,ipv6 host ,ipv6 route)
admin@PicOS-OVS$ovs-ofctl del-flows br0
ssun@dev-42:~/ryu/ryu/app$ ryu-manager simple_switch_13_ssun_buffer_mode5.py
for j in range(0,51):
for i in range(0,255):
output_port=78
tmp1='%d' %i
tmp2 = '%d' %j
ipv4_dst='192.168.' + tmp2 +' .' +tmp1
dl_dst="22:22:22:22:22:22"
vlan_vid=20
match=self.set_match(datapath, dl_type=0x0800, ipv4_dst=ipv4_dst, ipv4_dst_mask="255.255.255.255")
actions=self.set_action(datapath, dl_dst="44:44:44:88:88:88", vlan_vid=vlan_vid, out_port=output_port)
self.add_flow(datapath, 252, 32768, match, actions)
Step 7: Check max ipv4 l3 flow members
admin@PicOS-OVS$ovs-ofctl dump-flows br0|grep -c "table=252" 12000 admin@PicOS-OVS$ovs-appctl pica/show tables Pica Tables Statistics: Pica Tables Max Limitation Current Used ----------------------------------------------------------------------- ICAP Table 2044 10 ECAP Table (null) (null) VCAP Table 512 0 L2 System Table 512 1 L2 FDB Table 32256 0 L3 Host Table 12000 IPv4(0),IPv6(0*2) L3 Route Table 12000 IPv4(12000),IPv6(0*2) UDF Table (null) (null)
