C: CAM control
Syntax:
8430-tool ethn -C arc [m|u] [2|7:1] MAC_addr
new type rule rmr rcr
rule rule_nmbr [on|off]
irq [on|off]
reset
Description:
This command option causes the driver to modify CAM entries to define ARC entries made up of
MAC addresses, to define or redefine CAM rules and to toggle on and off any CAM rule.
Operands:
arc [m|u] [2|7:2] MAC_addr
Keyword specifying the insertion of a MAC address into one of 6
unicast arc entries or into the single multicast arc entry. The first
unicast arc entry is occupied by the MAC address of the local device.
m indicates insertion into the multicast arc entry. u indicates insertion
into one of the six unicast entries.
m for multicast requires 2. u for unicast allows 7 down through 2. Note
that unicast entry 1 is already occupied by the local MAC address.
MAC_addr specifies the MAC address to be added to the ARC filter.
new type rule rmr rcr
Keyword specifying the overlay of a particular CAM rule.
type is one of the types given by the –c types command described
above.
rule
specifies the number of the rule to be modified or redefined.
rmr specifies the CAM RMR register value.
rcr
specifies the CAM RCR register value.
rule rule [on|off]
Keyword to toggle a CAM rule on or off.
rule specifies the number of the rule to be toggled on or off.
[on|off] toggles the rule specified by rule rule on or off.
irq [on|off]
Toggles Classification Interrupt generation. on enables Classification
Interrupt generation. off disables Classification Interrupt generation.
reset
Resets all CAM rules to the hardware default and then reinitializes the
interface's MAC address as the first ARC entry. (The MAC address is
normally taken from the EEPROM.)
f: IP Firewall
Syntax:
8430-tool ethn -f [on|off]
Description:
This command option causes the driver to activate or deactivate an IP firewall filter defined to block
local host DOS attacks.
Operands:
[on|off]
Toggles the firewall filter on or off.
