FDB probe commands -- debugging system internal fdb

Use debugging system internal fdb to enable forwarding database (FDB) debugging.

Use undo debugging system internal fdb to disable FDB debugging.

Syntax

Centralized devices:

debugging system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb { all | drv | entry [ verbose ] [ acl acl-number ] }

undo debugging system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb { all | drv | entry [ verbose ] [ acl acl-number ] }

Distributed devices in standalone mode:Centralized IRF devices:

debugging system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb { all | drv | entry [ verbose ] [ acl acl-number ] } slot slot-number [ cpu cpu-number ]

undo debugging system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb { all | drv | entry [ verbose ] [ acl acl-number ] } slot slot-number [ cpu cpu-number ]

Distributed devices in IRF mode:

debugging system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb { all | drv | entry [ verbose ] [ acl acl-number ] } chassis chassis-number slot slot-number [ cpu cpu-number ]

undo debugging system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb { all | drv | entry [ verbose ] [ acl acl-number ] } chassis chassis-number slot slot-number [ cpu cpu-number ]

Default

FDB debugging is disabled.

Parameters

mac-forwarding: Specifies the Layer 2 FDB debugging. To enable Layer 3 FDB debugging, do not specify this keyword.

ipv4: Specifies the FDB by IPv4 address.

ipv6: Specifies the FDB by IPv6 address.

all: Enables all types of debugging.

drv: Enables drive debugging.

entry: Enables FDB entry debugging.

verbose: Enables detailed FDB debugging.

acl acl-number: Specifies an ACL by its number.

· 2000 to 2999 for basic ACLs.

· 3000 to 3999 for advanced ACLs.

slot slot-number: Specifies a card by its slot number. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (Distributed devices in IRF mode) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot. Support for this option depends on the device model.

FDB probe commands -- display system internal fdb

Use display system internal fdb to display FDB information.

Syntax

Centralized devices:

display system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb statistics

Distributed devices in standalone mode:Centralized IRF devices:

display system internal [ mac-forwarding ] { ipv4 | ipv6 } fdb statistics slot slot-number [ cpu cpu-number ]

Distributed devices in IRF mode:

slot slot-number: Specifies an IRF member device by its member ID. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (Distributed devices in IRF mode) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot. Support for this option depends on the device model.

Parameters

mac-forwarding: Displays the Layer 2 FDB statistics. To display Layer 3 FDB statistics, do not specify this keyword.

ipv4: Specifies the FDB by IPv4 address.

ipv6: Specifies the FDB by IPv6 address.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command clears FDB statistics for all cards. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command clears FDB statistics for all member devices. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. On an IRF fabric, this command clears FDB statistics for all member devices if you do not specify a member device. On an IRF 3 system, this command clears FDB statistics for all IRF member devices and PEXs if you do not specify an IRF member device or PEX. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command clears FDB statistics for all cards. (Distributed devices in IRF mode) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. On an IRF fabric, this command clears FDB statistics for all cards if you do not specify a card. On an IRF 3 system, this command clears FDB statistics for all cards and PEXs if you do not specify a card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot. Support for this option depends on the device model.
