10G-T トランシーバの制限
Transceiver Compatibility and Interoperability からの転載です。
10G-T は LDPC 符号化などによる高負荷により、消費電力が高く熱を持つため制限があります。

コマンド TIPS
configure session で commit が使える
Juniper と異なり、startup-config には別途保存する必要がある。
commit check は存在しない。また、session history に履歴が保存される。
#configure session R(config-s-s1)#logging host 1.1.1.1 (config-s-s1)#show run | in logging (config-s-s1)#commit #show run | in logging logging host 1.1.1.1
rollback でコンフィグの切り戻しができる
以下は running-config の動作がうまくいかなかったとき、startup-config に戻すコマンドの例。
configure session モード
(config-s-s3)#rollback flash:startup-config
特権モード
#configure replace flash:startup-config
show configuration session history で、commit した履歴を確認し、任意の場所に rollback も可能。
#show configuration sessions history
Commit Hash Session Name User Description Commit Time Commit Cancel
Timer Expiry

show running-config section <target> で対象のコンフィグのみ表示できる
Cisco IOS とは異なり、route-map や再配布している別のプロトコル、SNMP の Trap も表示対象となる。
<target> 自体は正規表現で match する行を抜き出す + 階層に入るための行を抜き出す、どいう動作が行われる。
show running-config | section <Filter_keyword> と同一の動作と思われる。
NX-OS と異なり、複数キーワード指定時に "" で括らなくてもよいのが便利。
#show running-config section logging logging buffered 1024000 logging monitor debugging logging host 1.1.1.1 logging host 1.1.1.2 logging host 10.253.0.51 logging facility local1 logging vrf MGMT local-interface Management1 #show run section logging host logging host 1.1.1.1 logging host 1.1.1.2 logging host 10.253.0.51
show active でいる階層のコンフィグのみ表示できる
グローバル コンフィギュレーション モードは不可。(多すぎるので意味がないと思われる)
以下は router ospf 1 の配下で実施した例。
(config-router-ospf)#show active router ospf 1 router-id 10.255.255.254 passive-interface default no passive-interface Port-Channel49.100 passive-interface Vlan1461 network 10.255.254.0/30 area 0.0.0.0 max-lsa 12000 default-information originate metric-type 1
show running-config diffs で startup-config との差分を簡易確認できる
(config)#logging host 1.1.1.1 (config)#show run diff --- flash:/startup-config +++ system:/running-config @@ -15,6 +15,7 @@ ! logging buffered 1024000 logging monitor debugging +logging host 1.1.1.1 logging host 10.253.0.51 logging facility local1 logging vrf MGMT local-interface Management1
show running-config interface や show interface Eth* status でも range 指定可能
