Cisco NCS 5000 Series User Manual

Regular Expressions in Configuration Groups
Regular expressions are used in configuration groups to make them widely applicable. Portable Operating
System Interface for UNIX (POSIX) 1003.2 regular expressions are supported in the names of configuration
statements. Single quotes must be used to delimit a regular expression.
Not all POSIX regular expressions are supported.Note
Regular Expressions for Interface Identifiers
Configuration groups do not accept exact interface identifiers. You must use a regular expression to identify
a group of interfaces that are applicable to the configuration group. The regular expression ‘.*’ is not allowed.
You must begin the regular expression for an interface identifier with an unambiguous word, followed by the
regular expression. For example, to configure Gigabit Ethernet interfaces, use the regular expression
'GigabitEthernet.*'.
To display a list of available interface types for your router configuration, enter interface ? at the configuration
group prompt:
RP/0/RP0/CPU0:router(config-GRP)# interface ?
ATM 'RegExp': ATM Network Interface(s)
BVI 'RegExp': Bridge-Group Virtual Interface
Bundle-Ether 'RegExp': Aggregated Ethernet interface(s)
GigabitEthernet 'RegExp': GigabitEthernet/IEEE 802.3 interface(s)
IMA 'RegExp': ATM Network Interface(s)
Loopback 'RegExp': Loopback interface(s)
MgmtEth 'RegExp': Ethernet/IEEE 802.3 interface(s)
Multilink 'RegExp': Multilink network interface(s)
Null 'RegExp': Null interface
PW-Ether 'RegExp': PWHE Ethernet Interface
PW-IW 'RegExp': PWHE VC11 IP Interworking Interface
Serial 'RegExp': Serial network interface(s)
tunnel-ip 'RegExp': GRE/IPinIP Tunnel Interface(s)
tunnel-mte 'RegExp': MPLS Traffic Engineering P2MP Tunnel interface(s)
tunnel-te 'RegExp': MPLS Traffic Engineering Tunnel interface(s)
tunnel-tp 'RegExp': MPLS Transport Protocol Tunnel interface
Although you are required to enter only enough characters for the interface type to be unique, it is
recommended that you enter the entire phrase. All interface types used in regular expressions are
case-sensitive.
Note
To specify a subinterface, prefix the expression with the characters \. (backslash period). For example, use
interface 'GigabitEthernet.*\..*' to configure all Gigabit Ethernet subinterfaces.
You can specify Layer 2 transport interfaces or point-to-point interfaces as shown in these examples:
group g-l2t
interface 'Gi.*\..*' l2transport
