이 문서에서는 NX-OS를 통한 문제 해결 환경을 개선할 수 있는 몇 가지 빠른 팁과 요령을 설명합니다.
16진수는 16진수를, 10진수는 12를 나타냅니다.

고유한 변수를 생성할 수도 있습니다.
1) 터미널 세션 시간 초과 방지:
N7k-LabSW# show terminal | i Timeout
Session Timeout: 30 minutes
N7k-LabSW# terminal session-timeout ?
<0-525600> Enter timeout in minutes, 0 to disable
N7k-LabSW# terminal session-timeout 0
N7k-LabSW# show terminal | i Timeout
Session Timeout: 0 minutes
2) 디스플레이 단말기의 너비/길이를 설정합니다.
긴 너비 출력의 새 줄로 출력을 나누지 않으려는 경우 유용합니다.
N7k-LabSW# show terminal | i Width

VRF는 가상 라우팅 및 포워딩을 의미합니다.
명령에 VRF <>를 추가하지 않고 특정 VRF에 대해 CLI를 실행합니다.
N7k-LabSW# routing-context vrf management
N7k-LabSW%management# sh ip route
IP Route Table for VRF "management"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>

VDC는 가상 디바이스 컨텍스트를 나타냅니다.
LC는 라인 카드를 의미합니다.
N7K는 Nexus 7000을 의미합니다.
LC에 연결되면 CLI는 기본 VDC와 관련하여 실행되거나 관련 명령에 대해 VDC 번호를 지정해야 합니다.
대신 라우팅 컨텍스트와 마찬가지로 VDC # 공간에서 CLI를 실행할 수 있습니다.
예:
N7k-LabSW# attach module 4
Attaching to module 4 ...
To exit type 'exit', to abort type '$.'

CPU는 중앙 처리 장치를 의미합니다.
이 명령은 CPU를 사용하는 프로세스를 5초마다(변경할 수 있음) 출력을 제공합니다.Linux top 명령과 동일한 출력입니다.
