The GLC-LH-SM SFP can operate with short SMF cable. The Receiver will accept a maximum optical signal power level of -3dBm. The maximum output power of the Transmitter for this SFP is -3dBm; so these SFPs over a short SMF fiber link do not require an attenuator.
This is different with the longer reach SFPs (such as GLC-ZX-SM; max Recv = -3dBm, max Transmit = +5dBm), where a 10dB attenuator should be added to short fiber spans.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to
login w/ SSH 1 or 2 to the device compare to IOS device. After
investigation, the there is 1s delay between the client KEXDH_INIT and

Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
