Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
In a managed repeater having an address learn capability wherein receipt at a particular port of a data packet having a received source address different from a stored source address associated with the particular port replaces the stored source address with the received source address, a source address locking circuit, comprising: a learn mode circuit for the particular port, for replacing the stored source address with the received source address when the stored source address does not match the received source address; and an address lock register for the particular port, coupled to said learn mode circuit, for storing a bit value to prevent said learn mode circuit from replacing the stored source address with the received source address.
Claim 2
Dependent Claim
119 words
In a managed repeater having an address learn capability wherein receipt at a particular port of a data packet having a received source address different from a stored source address associated with the particular port replaces the stored source address with the received source address, a source address locking circuit, comprising: a learn mode circuit for the particular port, for replacing the stored source address with the received source address when the stored source address does not match the received source address; and an address lock register for the particular port, coupled to said learn mode circuit, for storing a bit value to prevent said learn mode circuit from replacing the stored source address with the received source address.
Claim 3
Dependent Claim
29 words
The source address locking circuit, as set forth in claim 1, wherein: said address lock register is externally programmable to set a time for disabling said learn mode circuit.
Claim 4
Dependent Claim
191 words
In a managed repeater having a plurality of ports and having an address learn capability wherein receipt at a particular port of a data packet having a received source address different from a stored source address associated with the particular port replaces the stored source address with the received source address, a source address locking mechanism, comprising: a plurality of learn mode circuits, one of said plurality of learn mode circuits corresponding to one of the plurality of ports, wherein each learn mode circuit replaces the stored source address with the received source address when the stored source address is different from the received source address and wherein the particular port associated with said learn mode circuit received the data packet; and a plurality of address lock registers, one of said plurality of address lock registers coupled to each learn mode circuit, for storing a bit value to prevent said learn mode circuit from replacing the stored source address with the received source address when the stored source address is different from the received source address and wherein the particular port associated with said learn mode circuit received the data packet.
Claim 5
Dependent Claim
191 words
In a managed repeater having a plurality of ports and having an address learn capability wherein receipt at a particular port of a data packet having a received source address different from a stored source address associated with the particular port replaces the stored source address with the received source address, a source address locking mechanism, comprising: a plurality of learn mode circuits, one of said plurality of learn mode circuits corresponding to one of the plurality of ports, wherein each learn mode circuit replaces the stored source address with the received source address when the stored source address is different from the received source address and wherein the particular port associated with said learn mode circuit received the data packet; and a plurality of address lock registers, one of said plurality of address lock registers coupled to each learn mode circuit, for storing a bit value to prevent said learn mode circuit from replacing the stored source address with the received source address when the stored source address is different from the received source address and wherein the particular port associated with said learn mode circuit received the data packet.
Claim 6
Dependent Claim
39 words
The source address locking mechanism, as set forth in claim 3, wherein: each of said address lock registers is independently and externally programmable to set a time for disabling said learn mode circuit associated with said address lock register.
Claim 7
Dependent Claim
39 words
The source address locking mechanism, as set forth in claim 3 wherein: said learn mode circuit further selects between replacing the stored source address with the received source address or with the programmed source address for the particular port.
