CLI Session Rules
Multiple CLI session support is based on the amount of available memory. The Resource Manager reserves enough
resources to support a minimum of six CLI sessions at all times. One of the six sessions is further reserved for use
exclusively by a CLI session on a Console serial interface.
resources to support a minimum of six CLI sessions at all times. One of the six sessions is further reserved for use
exclusively by a CLI session on a Console serial interface.
Additional CLI sessions beyond the pre-reserved limit are permitted if sufficient management resources are available. If
the Resource Manager is unable to reserve resources for a CLI session beyond those that are pre-reserved, users with
administrator-privileges are prompted to create the new CLI session, even without reserved resources.

ASR 5000 Interface and Port Rules
The rules discussed in this section pertain to the following Ethernet line cards and their interfaces regardless of the
application.
application.
Fast Ethernet 10/100 (FELC/FLC2)
Gigabit Ethernet 1000 (GELC/GLC2)
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:
Gigabit Ethernet line cards:
Give all logical interfaces a unique name to identify the interface from others in the same context. Logical
interfaces in different contexts may have the same name.
A single physical port can support multiple logical interfaces when you configure VLAN tags for that physical
port. You can use VLAN tagging to bind a single physical port to multiple logical interfaces that reside in
different contexts.
different contexts.
Assign all logical interfaces a valid IP address and subnet.
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 can configure a logical interface in only one context, but you can configure multiple interfaces (up to 512
Ethernet or 1,024 ATM) in a single context.
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 of 1,024
VLAN tags.
Each physical port on an Fast Ethernet 10/100 Line card may contain up to a maximum of 256 VLAN tags.
