telnet6-server
Syntax [ no ] telnet6-server
Context config>system>security
Description
This command enables Telnet IPv6 servers running on the system.
Telnet servers are off by default. At system startup, only SSH servers are enabled.
Telnet servers in 7705 SAR networks limit a Telnet client to three retries to log in. The Telnet server
disconnects the Telnet client session after three retries.
The no form of the command disables Telnet servers running on the system.
Default
no telnet6-server
vprn-network-exceptions
Syntax vprn-network-exceptions [ number seconds ]
no vprn-network-exceptions
Context config>system>security
Description
This command configures the rate at which the 7705 SAR sends ICMP replies to a source IP address
in response to TTL expiry IP packets that have been received for all VPRN instances in the system and
from all network IP interfaces. Packets include labeled user packets as well as ping and traceroute
packets within a VPRN.
This command does not apply to MPLS packets or service OAM packets such as VPRN ping and trace,
LSP ping and trace, and VCC ping and trace.
When the command is issued without any number and seconds parameters specified, the default rate
is 100 ICMP reply packets sent per 10 seconds. The no form of the command disables the rate-limiting
of ICMP replies.
Default
no vprn-network-exceptions
