in-path hw-assist edit-rule
Provides an optional text description of the specified rule.
Syntax
in-path hw-assist edit-rule rulenum <rule-number> description "<description>"
Parameters
rulenum <rule-number> | Specifies the rule number. |
description "<description>" | Specifies the description. The text must be enclosed in quotation marks. |
Usage
This feature functions only on a SteelHead or SteelHead Interceptor equipped with one or more Two-Port SR Multimode Fiber 10 Gigabit-Ethernet PCI-E or Two-Port LR Single Mode Fiber 10 Gigabit-Ethernet PCI-E cards.
Hardware Assist rules can automatically bypass all UDP (User Datagram Protocol) connections. You can also configure rules for bypassing specific TCP (Transmission Control Protocol) connections. Automatically bypassing these connections decreases the work load on the local SteelHeads because the traffic is immediately sent to the kernel of the host machine or out of the other interface before the system receives it.
Note: For a hardware assist rule to be applied to a specific 10G bypass card, the corresponding in-path interface must be enabled and have an IP address.
If the system is not equipped with the necessary card, an error message displays.
Example
amnesiac (config) # in-path hw-assist edit-rule rulenum 5 description "This rule enables automatic passthrough for all UDP connections"
