Top: Both X-chromosome territories are detected by FISH. Shown is a single optical section made with a confocal microscope. Bottom: Same nucleus stained with DAPI and recorded with a CCD camera. The Barr body is indicated by the arrow, it identifies the inactive X (Xi). Left: DAPI stained female human fibroblast with Barr body (arrow). Right: histone macroH2A1 staining. Arrow points to sex chromatin in DAPI-stained cell nucleus, and to the corresponding sex chromatin site in the histone macroH2A1-staining.
Usage Guidelines. Up to 16 security levels can be configured using Cisco IOS software. If such levels are configured on a system, using this command with the privilege-level option allows you to exit to a lower security level. If a level is not specified, the user will exit to the user EXEC mode, which is the default.
All HSRP commands are configured under the interface configuration mode of a router. To configure HSRP, issue the standby [group-number] ip [ip-address] command and assign the virtual IP address for a group.Use the same group number and virtual IP address on other routers, which provide redundancy for that group. This is the only command that is necessary to enable HSRP.rom the group of routers configured in a HSRP group, one router is elected as the active router and another as a standby router. The active router assumes the role of forwarding packets sent to the virtual IP address.
