TAP Series Switch Command Line Reference
wildcard bits is 0x0-0xFFFFFF
VSID is located in the low 24 bit of GRE head.
VSID value and wildcard bits both have 24
bits, If a bit in wildcard is 0 means this bit
needs to check, otherwise this bit should be
ignored.
Parameter
“
any
”
indicates packets with any
nvgre vsid value can match this rule.
src ip ( IP_ADDR IP_ADDR_WILD | any |
host IP_ADDR )
Specify the source IPv4 address of the flow
rule.
Use an IPv4 address and an IPv4 address
wildcard to specify a network (e.g.
192.168.1.1 0.0.0.255). If a bit in wildcard is
0 means this bit needs to check, otherwise
this bit should be ignored.
Use the parameter
“
host
”
and an IPv4
address to specify an exactly address.
Use the parameter
“
any
”
to indicate packets
with any source IPv4 address value can
match this rule.
dst ip ( IP_ADDR IP_ADDR_WILD | any |
host IP_ADDR )
Specify the destination IPv4 address of the
flow rule.
Use an IPv4 address and an IPv4 address
wildcard to specify a network (e.g.
192.168.1.1 0.0.0.255). If a bit in wildcard is
0 means this bit needs to check, otherwise
this bit should be ignored.
Use the parameter “host” and an IPv4
address to specify an exactly address.
Use the parameter “any” to indicate packets
with any destination IPv4 address value can
