Line Card Rules

• Quad Gigabit Ethernet (QGLC)
• 10 Gigabit Ethernet Line Card (XGLC)
Line Card Rules
The following engineering rules apply to the Fast Ethernet 10/100, Gigabit Ethernet 1000, Quad Gigabit
Ethernet and 10 Gigabit Ethernet line cards:
• Give all logical interfaces a unique name to identify the interface from others in the same context. Logical
• A single physical port can support multiple logical interfaces when you configure VLAN tags for that
• Assign all logical interfaces a valid IP address and subnet.
• You can configure a logical interface in only one context, but you can configure multiple interfaces (up
• You can apply a maximum of 128 access control list (ACL) rules to a single logical interface.
• All ports are identified by their <slot#>/<port#>.
• Each physical port on a Gigabit Ethernet 1000 or Quad Gigabit line card may contain up to a maximum
• Each physical port on an Fast Ethernet 10/100 Line card may contain up to a maximum of 256 VLAN
• The total number of VLANs untagged and/or tagged on each Fast Ethernet 10/100 Line Card must not
• A logical interface is limited to using a single VLAN or ATM PVC on a single physical port, identified

physical port. You can use VLAN tagging to bind a single physical port to multiple logical interfaces
that reside in different contexts.
• Give each logical interface within a context a unique IP address(es). Logical interfaces in different
contexts can have the same IP address(es).
• If multi-homing is supported on the network, you can assign all logical interfaces a single primary
IP address and up to 16 secondary IP addresses.

• You must configure the active line card only. In the event of a failover, all relevant information
(including the IP address) is transferred to the standby line card.
• Half-height line cards must installed in the upper and lower chassis slots behind a sa packet processor
card must be of the same type: FELC/FLC2,GELC/GLC2, or QGLC line cards.
