First Claim
Patent Images
1. A network device for processing packets, the network device comprising:
- an ingress module for performing switching functions on an incoming packet;
a memory management unit for storing packets and performing resource checks on each packet; and
an egress module for performing packet modification and transmitting a modified packet to an appropriate egress port;
wherein the egress module is configured to send an unmodified version of the incoming packet to an ingress mirrored-to-port when an ingress port, upon which the incoming packet is received, is configured to mirror packets received by the ingress port.

Abstract
A network device for processing packets includes an ingress module for performing switching functions on an incoming packet, a memory management unit for storing packets and performing resource checks on each packet and an egress module for performing packet modification and transmitting a modified packet to an appropriate egress port. The egress module is configured to send an unmodified version of the incoming packet to an ingress mirrored-to-port when an ingress port, upon which the incoming packet is received, is configured to mirror packets received by the ingress port.

10. A method for processing packets in a network device, the method comprises the steps of:
-
receiving an incoming packet;
storing the incoming packet;
performing resource checks on the incoming packet;
modifying the incoming packet to form a modified packet;
transmitting the modified packet to an appropriate egress port, sending an unmodified version of the incoming packet to an ingress mirrored-to-port when an ingress port, upon which the incoming packet is received, is configured to mirror packets received by the ingress port. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An apparatus for processing packets in a network device, the apparatus comprising:
-
receiving means for receiving an incoming packet;
storing means for storing the incoming packet;
checking means for performing resource checks on the incoming packet;
modifying means for modifying the incoming packet to form a modified packet;
transmitting means for transmitting the modified packet to an appropriate egress port, sending means for sending an unmodified version of the incoming packet to an ingress mirrored-to-port when an ingress port, upon which the incoming packet is received, is configured to mirror packets received by the ingress port. - View Dependent Claims (19, 20, 21, 22, 23)
