By default. Cisco NX-OS Commands Might Differ from Cisco IOSBe aware that the Cisco NX-OS CLI commands and modes might differ from those commands and modes used in the Cisco IOS software. No Spanning Tree ProtocolThe Cisco Nexus 1000V for VMware forwarding logic is designed to prevent network loops; therefore, it does not use the Spanning Tree Protocol. Packets that are received from the network on any link connecting the host to the network are not forwarded back to the network by the Cisco Nexus 1000V. Cisco Discovery ProtocolThe Cisco Discovery Protocol (CDP) is enabled globally by default. CDP runs on all Cisco-manufactured equipment over the data link layer and does the following: Advertises information to all attached Cisco devices. Discovers and views information about those Cisco devices. CDP can discover up to 256 neighbors per port if the port is connected to a hub with 256 connections. Note If you disable CDP globally, CDP is also disabled for all interfaces. For more information about CDP, see the Cisco Nexus 1000V System Management Configuration Guide. DHCP Not Supported for the Management IPDHCP is not supported for the management IP. The management IP must be configured statically. Upstream Switch PortsWe recommend that you configure spanning-tree port type edge on upstream switches for faster convergence. The following commands are available to use on Cisco upstream switch ports in interface configuration mode: spanning-tree portfast spanning-tree portfast trunk spanning-tree portfast edge trunk InterfacesWhen the maximum transmission unit (MTU) is configured on an operationally up interface, the interface goes down and comes back up. Supported MTU values vary according to underlying physical NIC capability. Layer 3 VSGWhen a VEM communicates with the Cisco Virtual Security Gateway (VSG) in Layer 3 mode, an additional header with 94 bytes is added to the original packet. You must set the MTU to a minimum of 1594 bytes to accommodate this extra header for any network interface through which the traffic passes between the Cisco Nexus 1000V and the Cisco VSG. These interfaces can include the uplink port profile, the proxy ARP router, or a virtual switch. Copy Running-Config Startup-Config CommandWhen you are using the copy running-config startup-config command, do not press the PrtScn key. If you do, the command aborts. SNMP User Accounts Must Be Reconfigured After an Upgrade If you are upgrading from a release earlier than 5.2(1)SV3(1.1), the SNMP engine ID changes internally to a unique engine ID. You must reconfigure all the SNMP user accounts to work with the new engine ID. Until the SNMP user accounts are reconfigured, all SNMPv3 queries fail. This restriction is associated with the defect CSCuo12696. After an upgrade, use the show snmp user command to view the engine ID: switch# show snmp user______________________________________________________________SNMP USERS______________________________________________________________ User Auth Priv(enforce) Groups____ ____ _____________ ____________________________________________________________________NOTIFICATION TARGET USERS (configured for sending V3 Inform)______________________________________________________________ User Auth Priv____ ____ ____admin md5 des(EngineID 128:0:0:9:3:2:0:12:0:0:0) Complete the following steps to reconfigure SNMP user accounts. Reconfiguring SNMP user account involves deleting and recreating a new SNMP username and password..

CDP is a Cisco proprietary Cisco CDP Client (the CDP Client of windows host) monitor the whole network. Cisco CDP Monitor is a highly efficient network monitor and troubleshooting tool.

目次1CDPの概要CDPでやり取りする情報CDPの無効化CDPの確認LLDPの概要CiscoルータやCatalystスイッチはCDP(Cisco Discovery Protocol)によって、自身を起点として直接接続されている他のCisco機器を検出することができます。直接接続されているデバイスのことを近接デバイスあるいは隣接デバイスと呼んでいます。CDPはデータリンク層で動作するCisco独自のプロトコルで、SNAPカプセル化をサポートする物理メディアで利用可能です。SNAPカプセル化をサポートする物理メディアは、イーサネット、フレームリレー、ATM、PPP/HDLCなどがあります。また、上位プロトコルには依存しません。Cisco独自のプロトコルなので、他のベンダのネットワーク機器やホストは検出できないので注意してください。CDPはデータリンク層のプロトコルなので、CDPで直接接続されている機器を検出できれば、データリンク層までは問題なく動作していることも確認できます。図 CDPの概要他のベンダのデバイスでもCDPをサポートしているものであれば検出可能です。Ciscoルータ/Catalystスイッチは、デフォルトでCDPが有効になっています。60秒ごとにCDPの情報を送信します。CDPの情報を送受信する際は、予約されたマルチキャストアドレス「01-00-0c-cc-cc-cc」を利用しています。CDPの情報を受信すれば、その内容をCDPのキャッシュに格納します。これを参照すれば、どのようなデバイスがどのポートに接続されているかがわかります。CDPのキャッシュを参照するには、show cdp neighborコマンドを利用します。定期的なCDPの情報を一定時間受信することができなければ、その情報をキャッシュから削除します。この時間のことをホールドタイムといい、デフォルトは180秒です。また、CDPはCatalystスイッチに接続されているCisco IP Phoneを検出するためにも利用します。Catalystスイッチに接続されているCisco IP PhoneへVoice VLANなどといったIP Phoneに必要な情報を通知できます。図 CDPとCisco IP PhoneCDPにはバージョン1とバージョン2があります。現在のCiscoデバイスはデフォルトでCDPバージョン2が有効になっています。CDPバージョン1では、次の情報が送受信されています。隣接デバイスIDローカルインタフェース隣接デバイスのケイパビリティ隣接デバイスのプラットフォームリモートインタフェース隣接デバイスのネットワーク層アドレス隣接デバイスのIOSバージョン情報これに加えて、CDPバージョン2では次の情報が追加されています。VTPドメイン名ネイティブVLANインタフェースの2重モードCDPでやり取りされる情報は、IOSバージョンやIPアドレスの情報が含まれています。そのため、不用意にCDPで情報を送信すると悪意のあるクラッカーに不正アクセスの足がかりとなる情報を与えてしまう可能性もあります。また、直接接続されている機器がCisco製以外であれば、CDPの情報を送信することは意味がありません。そこで、CDPの有効化/無効化をコントロールする必要があります。CDPを無効化するには、グローバルコンフィグレーションモードで次のコマンドを入力します。(config)#no cdp run再びCDPを有効にするには、cdprunコマンドを入力します。そして、インタフェース単位でもCDPを無効化することができます。CDPを無効にしたいインタフェースコンフィグレーションモードで次のコマンドを入力します。(config-if)#no cdp enableこの設定により、該当のインタフェースからCDPの情報を送信することをとめることができます。再びCDPを有効にするにはcdp enableコマンドを入力してください。CDPで直接接続されているCisco機器を確認するには、主に次のコマンドを利用します。#show cdp neighbor [detail]#show cdp entry 以下は、show cdp neighborの出力例です。CenterRT#show cdp neighbors Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone, D - Remote, C - CVTA, M - Two-port Mac Relay Device ID Local Intrfce Holdtme Capability Platform Port IDSwitch Gig 0 179 S I WS-C2960S Gig 1/0/1show cdp neighborコマンドを実行している機器のホスト名はCenterRTです。CenterRTはSwitchと直接接続されています。接続しているインタフェースは、以下のとおりです。CenterRT GigabitEthernet0 (Local Intrfce)Switch GigabitEthernet1/0/1(Port ID)また、PlatformからSwitchはCatalyst2960Sであることもわかります。図 CDPで確認した機器同士の接続CDPの詳細な情報を確認するには、show cdp neighbor detailまたはshow cdp entry コマンドです。CenterRT#show cdp neighbors detail -------------------------Device ID: SwitchEntry address(es): 10.0.0.100Platform: cisco WS-C2960S-24TS-L, Capabilities: Switch IGMP Interface: GigabitEthernet0, Port ID (outgoing port): GigabitEthernet1/0/1Holdtime : 177 secVersion :Cisco IOS Software, C2960S Software (C2960S-UNIVERSALK9-M), Version 15.0(2)SE2, RELEASE SOFTWARE (fc1)Technical Support: (c) 1986-2013 by Cisco Systems, Inc.Compiled Tue 05-Feb-13 12:48 by prod_rel_teamadvertisement version: 2Protocol Hello: OUI=0x00000C, Protocol ID=0x0112; payload len=27, value=00000000FFFFFFFF010231FF00000000000070105C247880FF0000VTP Management Domain: 'cisco'Native VLAN: 1Duplex: fullshow cdp neighbor detailコマンドでは、IPアドレスやIOSバージョン、VTPドメイン、ネイティブVLAN、デュプレックスなどのさまざまな情報もわかります。CiscoのCDPに相当する標準化されたプロトコルがLLDP(Link Layer Discovery Protocol)です。LLDPはIEEE802.1ABで標準化されています。LLDPはCDPと同様にデータリンク層で動作します。LLDPが有効な機器同士でLLDPフレームを交換することで、直接接続している機器を検出したり、追加の設定情報を通知することができます。Cisco Catalystスイッチでは、LLDPをサポートしているモデルでもデフォルトでは、LLDPは無効化されています。LLDPを有効にするには、グローバルコンフィグレーションモードで次のコマンドを利用します。(config)#lldp runまた、CDPと同様にインタフェース単位での設定も可能です。インタフェース単位でLLDPを設定するには、インタフェースコンフィグレーションモードで次のコマンドを利用します。(config-if)#lldp [transmit | recieve]
