Description
Configure Layer 2 address learning and forwarding properties globally.
The remaining statements are explained separately. See CLI Explorer.
Options
| global-le-bridge-domain-aging-time |
Specify the aging time of LE bridge-domain. The MAC address is learnt after next hop(NH) and bridge-domain(BD), also called NHBD. This aging time delays the deletion of NHBD. Configuring lesser time, in seconds, results in faster deletion of NHBD.
|
| global-ctx-limit |
Specify the debug context history limit. It is the limit for the number
of events that are logged in the process memory for debug purposes. The
value '0' to '5000000' is the number of events captured in the process
memory. Each event entry takes upto 200 Bytes of memory. By default,
256000 entries are saved to log the events that happen in the Layer 2
process. You may disable the feature by setting
