Usage
Information
Only if you enable the port security, you will be able to configure MAC address learning limit
configurations on the interface level.
When you disable the port security, all the interface level configurations are reset. Also, all dynamically
learnt MAC addresses on the interfaces configured with MAC address learning limit are cleared.
show cam mac linecard (dynamic or static)
Display the CAM size and the portions allocated for MAC addresses and for MAC ACLs.
C9000 Series
Syntax
show cam mac linecard slot-id port-set port-pipe [address mac_addr |
dynamic | interface interface | static | vlan vlan-id]
Parameters
linecard slot-id (REQUIRED) Enter the keyword linecard then a slot number to select the
linecard for which to gather information. The range of C9000 slot IDs are from 0 to
11.
port-set port-
pipe
(REQUIRED) Enter the keywords port-set then a port-pipe number to specify
the port pipe for which to gather information. The range of port pipe numbers is
from 0 to 0.
address mac-
addr
(OPTIONAL) Enter the keyword address then a MAC address in the
nn:nn:nn:nn:nn:nn format to display information on that MAC address.
dynamic (OPTIONAL) Enter the keyword dynamic to display only those MAC addresses
the switch dynamically learns.
interface
interface
(OPTIONAL) Enter the keyword interface then the interface type, slot and port
information:
● For a Port Channel interface, enter the keywords port-channel then a
number.
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port information.
● For a port extender Gigabit Ethernet interface, enter the keyword peGigE then
the pe-id / stack-unit / port-id information. The pe-id range is from 0 to 255;
the stack-unit unit-number range is from 0 to 7; and the port-id range is from 1
to 48.
● For a port extender 10-Gigabit Ethernet interface, enter the keyword
peTenGigE then the pe-id / stack-unit / port-id information. The pe-id range
is from 0 to 255; the stack-unit unit-number range is from 0 to 7; and the port-
id range is 25 to 28 or 49 to 52 depending on the PE.
static (OPTIONAL) Enter the keyword static to display only those MAC addresses
specifically configured on the switch.
vlan vlan-id (OPTIONAL) Enter the keyword vlan then the VLAN ID to display the MAC
address assigned to the VLAN. The range is 1 to 4094.
