Usage guidelines
If automatic bandwidth adjustment is enabled, bandwidth tuning happens every 24 hours without upper
and lower bandwidth limits.
Automatic bandwidth adjustment cannot be used together with the mpls te reoptimization, mpls te
route-pinning, mpls te backup, and mpls te resv-style ff commands.
Examples
# Automatically tune bandwidth for tunnel 0 hourly.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] mpls te auto-bandwidth adjustment frequency 3600

Default command level
2: System level
Parameters
hot-standby: Sets the tunnel backup mode to hot backup. In this mode, a backup CR-LSP is established
immediately after the primary CR-LSP is established. When the primary CR-LSP fails, MPLS TE
immediately switches services to the backup CR-LSP.
ordinary: Sets the tunnel backup mode to ordinary backup. In this mode, a backup CR-LSP is established
only when the primary CR-LSP fails.
Usage guidelines
When backup is enabled, the record route flag is automatically set to record reroute regardless of
whether the mpls te record-route command is configured.
The mpls te backup command cannot be used together with the mpls te reoptimization, mpls te
auto-bandwidth adjustment, and mpls te resv-style ff commands.
Examples
# Enable hot backup for Tunnel0.
<Sysname> system-view
[Sysname] interface tunnel 0
